FORD 351W VS 351C

This is an overview of some of the Ford engine Family's I will try to clear up some of the confusion

[@gergatronic]

Hi folks, hailing from Australia. We've had a strong following of Clevelands over here over the years due to Ford Australia producing its own version of the Clevo. We started making them from '72 onwards; the 351 and a de-stroked 302 version, same bore/stroke as the 302W. Think of it as what a 351M is to a 400. It used unique crank and rods. Our blocks were based on the "square" casting (71 onwards), but the US tooling was unsuitable for our iron which was extremely hard and caused premature tool wear. Our tooling had to be revamped to suit. We had many Ford Aus parts unique to our market, for instance: 4-barrel square bore manifolds with 2V ports, (73-76), spreadbore were made from 76 onwards for both 302 and 351. All 302s and non-GT 351s were 2-barrels up until then. These 4 barrel manifolds were good for maybe a shade over 400hp. Imported 4V engines were fitted to GT Falcons until 74. The 302 used a uniquely cast head that didn't exist in the US. The head was a 2V but had closed 58cc chambers, smaller than the early 4Vs. These were highly prized in the US before affordable aftermarket ones became available. 302s also had longer 6.030" rods, which are also handy to use in a long-rod 351 build using specific ACL high-gudgeon pistons. All Aussie blocks were 2 bolt mains except for some later "pillow" blocks intended for NASCAR use. These had enlarged water jackets, beefier pan rails and filled-in webbing around the main journal area. The special run of NASCAR blocks were largely rejected due to excessive core shift. They were instead used in F-truck ambulances and DeTomaso Panteras until stocks ran out in 1988. The last Falcon/Fairmont with a Clevo left the factory in late 82. The idea of a 302C sounds goofy just to have a smaller V8 option but with the reduced torque, they could use the smaller 6-cylinder drivetrain behind it (instead of toploader/C6/9 inch) to keep build costs down. I have a 302C in my 82 wagon, and it goes ok. Ports probably too big for that displacement in a daily rig but does make the right noise 😁👍🏼

[@paulflanagan4002]

Indeed. I had a buddy in Melbourne ship me a set of 302 Cleveland heads for my 351C Stock Car engine. Bolt on 75 Horsepower!

[@roberthoffrichter287]

The block you talked about with the field in Maine wedding in the 4 bolt main we call that a boss block, but then they had some early NASCAR setups to that were a little bit different I'm new to this Cleveland stuff the heads flow good they make power but they could have done so much better with the four we had I mean the inside middle cylinders have a pushrod coming down to the edge of the porting p there's so many things you have to put a Band-Aid over bad engineering yet they got away with it but it could have been so much better. Imagine if the engineers had been on par with today's AFR HEADS, we would easily be sporting 550-600 horsepower, considering you can build a 302 dart block with AFR 205cc renegade competition heads and make 550 horsepower imagine what could have been done back then if they did just got the engineering right with the porting in the heads

[@MustangsTrainsMowers]

Did Ford make any of the 300-6’s in Australia? I remember seeing a cab over farm truck with a 300-6 during either my 1999 or 2002 trips to Australia. My dad and his 2nd wife had a farm in the Gippsland area of Victoria.

[@YouScroob]

A few notes from memory, I worked on these in Winston Cup in the mid '70s. The Windsor has a higher deck (I think .900) than the Cleveland or the 302 which were the same. You can put the Cleveland head on a Windsor but it takes a lot of work. The guy I worked for was Parky Nall. He developed what he called the "Windsor Boss". To put the head on, I first plugged the water passage to the block with a pipe plug. Then I drilled and tapped new water passages in the front of the heads and we made a water manifold from copper tubing . Spacer plates are required for the intake manifold (I think they were aluminum about 5/8" thick) We used various manifolds from the Boss 302 and 351C. We used the Windsor blocks because with the improved casting process of the Cleveland block, the cylinder walls were too thin for racing. We tried the Cleveland block but always broke cylinder walls. I also added 4 bold caps to the Windsor blocks. On short tracks we could get away with the cast Windsor cranks, but in Cup we used aftermarket billet cranks. On the Boss head we did not really touch the intake ports as they were too big for even Talladega or Daytona. That is the main reason the Chevys won more on the short tracks then. These are the main things I remember doing to build that engine. We were a job shop located in Charlotte, and were not connected with any one team. We built Ford and Chevy engines. We built the engine on the pole for the '76 Daytona 500 (Ramo Stott - Chevy) 550 HP. The Windsor Boss we were building at that same time was 575 HP.

[@fk4515]

Windsor is in Ontario, Canada not Michigan. Ford FE engines (Ford Edsel) and came in 11 different displacements, also spattered in there was 4 displacements that were tagged FT (Ford Truck) the FE was intended to be the replacement for the Y block. FE displacements range from 330 to 427. Introduced at the same time as the FE was the MEL (Mercury Edsel Lincoln) engine that looked like an oversized FE and had displacements from 383 cubic inches to 462 cubic inches and a Super Duty an engine made for truck with a displacement from 401 to 534 cubic inches.

[@dickjones6159]

oh and the 428 was not a FE.. come on man.

[@CJ-ib2jy]

@@dickjones6159 I think he is talking actual displacement and not advertised displacements. A 428 FE actually has 427 cubic inches. The old 427 FE actually had 425 inches but GM already had a 425 and Chrysler had a 426 so Ford advertised that motor as a 427. Later when Ford built a true 427 inch long stroke motor for their heavier cars, they called it a 428 to distinguish it from their 427 FE high performance motors.

[@rustybritches6747]

yea Windsor Ontario Canada not Michigan that's what I always was told this guy definitely knows his stuff but I think you might be wrong on that little bit of information which really doesn't make a difference I still have much respect for this man! edit: I just looked it up to double-check and it is Windsor Ontario Canada Windsor Township Michigan does not have a Ford plant!

I worked for Navistar in the late 90's manufacturing the 7.3 Powerstroke for Ford. I visited the Windsor plant several times in Canada. But it is very close to Detroit. I spent too much time at Cheetah's in Windsor. lol

[@briandietrich1373]

My dad and I back in the early 80's rebuilt a 77 400. We only did a mild performance makeover on it, as it was for our F-250. Huge difference with bumping the compression to 9.5:1, mild truck cam. Kept the stock 2V carb That truck would smoke the back tires like no tomorrow! I think these engines are hidden gems. I think the early smog controls neutered them

We can thank the Australian after market for keeping the Clevo alive!

[@indridcold8433]

The Cleveland is the large block. I wonder why there seems to be less support for the Cleveland than for the Windsor.

[@PatriotPaulUSA]

@@indridcold8433 Not True a Cleveland is a small block. It uses a small block trans and a 289 head will phisically bolt onto a 351c but water passages are opposite because a Cleveland was designed for racing with a dry intake.Water flows thru the Windsor intake. Today's Nascar motors are all basically derived from a ford 351C head/intake design because it flows the best and that makes horsepower. Look at them all sometime and you can see. Bill Elliot proved it in the 80s when he went well over 212. mph with his steel thunderbird at Talladaga I believe. Sorry I'm not a Nascar junkie.

[@Mercmad]

True !with lots more development than was ever carried out in the USA . When the rest of the hotrodding world were messing with SBC's a few enlightened souls in Australia were having a great time with their clevos.

I wish I could take your ford kniwledge and plant it in my brain. Keep up the videos. You’re teaching me a ton that the majority of people don’t even know to teach

[@lelandlewis7207]

Firstly, and maybe someone already mentioned it, the Windsor plant is in Windsor, Ontario, Canada, where they also made the Essex engines. You also missed mentioning two of the most famous FE engines, the 427 and the 406. The Cleveland heads came in a variety of designs. The 4V closed and open chamber, the 2V closed and open chamber and the Boss heads which had screw-in rocker studs. For a good street 351 or 302, the 2V has better torque while still making lots of HP, especially on a 302, and in either head, the closed chamber is better due to its quench area. For a large cube motor, which head you use depends on the RPM and what you are building it to do. A 4V Cleveland head can move a lot of air, out-flowing a 427 rectangular port BB Chev, so you can see why it is a good horsepower and higher RPM head, but, also, not necessarily the best head for a street/strip stormer where you want torque and can't use the RPM. Also, for a heavy vehicle or a stump-puller, the 2V may be a better choice. The 2V closed chamber is a rare bird, I believe, only in Australia, where they also had a slightly different 302 Boss head. Australia used the Cleveland a lot longer than in the US, probably due to laxer emission regulations. The 351W head everyone used to want is the 1969 4V head. It can be identified by 4V cast into it and adjustable rockers. Later on, everyone started looking for the GT40 head, which can also be found on some trucks. Also, 351W has two different deck heights, so if you are building one, be sure to know which one you have before ordering pistons. I built one with the tall piston in the short block and the piston stuck out of the block a few thousandths. It went over 100,000 miles in a delivery truck and the owner was very impressed with the torque, but, in a performance engine, it probably would have destroyed itself at higher RPM.

[@rexmilanista]

You forgot to mention that 351c heads can be mounted on a Windsor block so long as the proper intake is used. Hence the Boss 302

[@yankeewatchdog7299]

...and the use of stepped head bolts

[@rodneytatman449]

Boss 302 came out first and it used 1/2" head bolts. Not the same as a Clevor.

[@lelandlewis7207]

@ , the smaller mains of the C are better at higher RPM. The larger the main the higher the friction factor and larger crank journals require a better oiling system due to the higher rate of cast-off of larger journals. Each of the 351s has its advantages, but, I have never seen a Cleveland fail due to a weak bottom-end.

[@royshashibrock3990]

My kind of video....all info and straight to the point. It also highlights the insanity of Ford in having so many block-head-manifold variations, while other makers tried to have just a few series of engines. Good video.

[@brianmaynard7320]

@fitty6pickemup I WISH!! I have a set of Aluminum Heads. Bare.. No vskbes.. All is to be determined

[@jamessnell105]

I drove a ‘78 Bronco with a 351M two barrel for ten years as my daily driver getting 6.5 mpg. The crankshaft broke while driving on the freeway at 70 mph. With 4:10 gears it was probably turning 3,500 to 4,000 rpm. I called a machine shop about rebuilding it and he told me exactly where the crankshaft broke before I was able to tell him. He convinced me to bore it 30 over and use the 400cu rotating assembly. I also had the stock heads ported. Used an aluminum after market four barrel intake and carb, added headers and also had a new cam installed that added duration with over lapping opening. I couldn’t add lift because with the longer stroke the valves would hit the pistons. That caused the engine to produce no vacuum that killed my brakes that had been awesome before that. I also made a mistake of using the four barrel head gaskets that blocked the water passages on the two barrel heads. It caused severe overheating quickly and I had to tear it back apart and change the head gaskets. I drove that Bronco for another nine years now getting 7mpg. The changes to the 351M really made a huge difference. I loved that truck and I regret selling it to this day. I had also lifted it 6” and had 36” tires on it. With 410 gears and front and rear posis in it, it would drive through anything. It drove through three foot deep snow like it wasn’t there and through rivers deep enough that the water was coming over the hood. I’m sure that if I had lost momentum the water would have swamped the motor. I keep my eyes open for another ‘78-‘79 Bronco but I haven’t been able to find one that I didn’t need a mortgage to buy it 😢.

[@davebridges2212]

I had a 351M in a 1979 Bronco that I bought, That would only get about 12 miles per gallon, and that was with a Holley 500 CFM 2 barrel on it. I pulled it out and upped the compression from the factory 7.9:1 to about 9 3/4:1, balanced and blueprinted and overbored .030". I put in a mild Comp Cam kit, aluminum dual plane intake with a Holley 780 carb, a set of long tube headers and dual 2 1/2" exhaust with a balance pipe and turbo mufflers. It run strong, I'm estimating about 350 HP, and still got 19 miles to a gallon. I knew the original owner of the Bronco and he couldn't believe I was getting that kind of mileage.

[@bradpittman5075]

Thankfully now days (2019) there is an enormous amount of aftermarket support for the small block ford w and c families. John Kasse has a head called the p38 which is basically a nice Cnc ported deal for a Windsor that uses the canted style valves like a Cleveland. Most windsor guys I know basically jump right to trickflow high ports for their engines but I am curious to see how those p38s would do.

[@MrSaturdayNightSpecial]

From what I can remember the Cleveland assembly plant used different heads, different valve style and cooked the blocks to a higher temp. There was also a difference in the valve cover bolts and the mains if I remember right. The bottom line for me was the higher block temp. Supposedly the Windsor's came factory with a little bit more power via the cams. Anyhow, thanks for clearing up some stuff. Great channel.

After it was built it was great for the above mentioned labors.After the build no matter what you did to the truck it got 16 mpgs towing, loaded, A/C on or off, up or down hill or sitting in the driveway not running 16mpgs. I found tons of aftermarket parts Comp Cams RV cam & alot of the aftermarket performance parts I still have some. I may save them to build another one since you shed a lot of light on the 351M.

[@davenhla8195]

Easiest way to wake up a 351/400M is to find a set of 351C 4V heads with the smaller combustion chambers. The 351C guys don't want them because the chamber is to small for high RPM power, BUT, if you stick them on a later 70's 351M, it bumps the compression up close to 9:1, and makes a BIG difference. The 4V heads can be found pretty cheap usually. There are better/more potent options, but then they cost more $. If you are just trying to make a snappy V8 on a budget, a 351m with 4v heads won't dissapoint.

[@Myvintageiron7512]

Agreed

[@Sokrates66]

Well, you are wrong. The small combustion chamber heads is the diamonds. All Cleveland builders want the so called closed chamber heads. All the other 351c heads is pretty much rubbish.

[@markgodfrey790]

Davenhla wrong dude...the 351c 4 v heads were used for racing. They had larger ports than the 2 v heads and they made top end power at higher rpms. Up to 8500 rpm. The Cleveland 2 v heads were better suited for Street because you didn't have to run them at such high rpm to get their potential peak power. The 351c was a race bred engine used in cars like the Pantera. Then were adapted for Street use. The 4 v heads were generally used with a single plane intake. The 2v head was used with a dual plane intake. The 2v head had 21/2 inch intake ports. And I've heard it said that you could fit a tennis ball inside the 4 v head intake ports but I don't know for sure about that or what the exact size of the ports were on the 4 v head. I just know that the 2 v head was better suited for Street use.

[@markgodfrey790]

Davenhla you are a little bit confused there dude...the 351 4v heads are for the higher revving race version of the 351 c. They have huge intake ports that are better suited for racing and high rpm . Up to 8500 rpm. I'm pretty sure the chamber size is the same on both heads but the 2 v heads have smaller intake ports to help create higher air velocity at lower engine rpms. When they are port matched to a medium rise dual plane intake manifold with a properly matched carburetor and cam it's a better choice for Street performance because it developed more torque and HP at lower more useful rpms...

[@todddenio3200]

The 351C 4V heads had intake ports that were about equal in size to the intake ports on the 429/460. Those things would REALLY BREATH at higher rpm's. They were pretty useless for street use though as street engines weren't going to be spun to over 7000 rpm.

[@AndieBlack13]

Multiple engine builders since the introduction of the canted-valve 351C ran into an apparently forgotten serious design flaw of the canted valve engines. (Note: Steve Christs book writes of this). This particular head design has the exhaust valve port turning 120 degrees, from the floor of the port to the point perpendicular to the valve. This sharp turn exiting the valve "stalls" the airflow, creating a turbulent flow along the bottom floor of the port...effectively making the port only 66% effective. Engine builders in the early "Pro-stock" series found by milling away the entire exhaust port, fabricating entire new ports, welded & machined in, changing the exit angle, could they get good flows from those ports...in stock configuration, getting good airflow is impossible, severely limiting power output.

[@Myvintageiron7512]

I agree the exhaust port on the Cleveland heads is a big drawback, I was able to get my % of flow up to 74% with a bigger ex valve and porting raise the port ceiling and blend it bowls but you are right by today's standards even 74% is pretty poor flow especially for all the work and time it takes to do it but you can improve them somewhat the best head we have found for making really good all around power are trick Flow's power Port Cleveland heads they work great for a street rod or can be used to race with a more aggressive cam/intake /compression ratio combo

[@charlesvan13]

I saw a video of some hot rod program where they built a 351 Cleveland and dynoed it with both 4V and 2V head. And, surprisingly, the only difference was a little more torque with the 2V. Apparently the ports are just too large on the 4V. The goal is airflow, and bigger doesn't mean better for ports.

The Cleveland borrowed many design cues from the BOSS 429 - HUGE ports and valves - plus, the Cleveland had the highest compression ratio of any Ford High Pereformance engine at 11.4:1 (source Ford 1970 model specs sept. 1969) That 351C became the workhorse of the '70's.

You are speaking of the Chrysler polyspherical 318. They were produced until 1966 I believe it was. They never used them in a serious high performance application so their potential was never realized. After that Chevy created the canted valve big blocks-396, 427 and 454.

As others below have mentioned there was another Cleveland block, the 302 and 351 Geelong thickwalled block cast in Geelong, Victoria Australia. These blocks did not suffer from casting cracking at the webb at rear like the Usa thinwall casting. The Australian 302 cu Cleveland, yes a 302 Cleveland was a destroked 351 , 3' stroke and 6 inch rod and had a 53 cc chamber head with the 2.02 intake valve, the Australian 351 heads had either 62 cc chambers or the big valve 58 cc 4v ported heads. The reason for the 302 was to delete having to supply a Windsor as a small block option and utilise same or similar components as the locally produced Cleveland. Ford F'series pickups F100, 150, 250 and 350 from 1978 - 1984 (i think) were fitted with Clevelands also. Place the small port 53 cc heads on a standard 8.9:1 or (9:1 or std Australian 9.5:1 351 block and voila an 11:1 comp very torquey engine that needs 100/130 Avgas but produces easy big hp. The HO 351 was also supplied in Australia in the 1972 - 1975 Ozzie GT Falcon 4 door, 10.75:1 comp and an underated 300hp that would rev to 6500 rpm if I remember correctly. At the time reputedly the fastest 4 door production car in the world, 145MPH ! You probably W'ONT see these Australian blocks or heads in this video.

When my '79 Bronco needed rebuilt I did basically what you are suggesting: 400 crank/rods/flat-top pistons/Cleveland heads/Edelbrock Performer manifold/Carter 4bbl, recurved distributor/headers/Magnaflow exhaust with a crossover/RV cam/slight lift on body. The thing had the four-sp'd trans and I rebuilt the rear-end with 31 spline axles. Wonderful rig with a ton of torque.....that long stroke really made a difference in grunt. Whenever it snowed quite a bit I would go up on the interstate with a couple of log chains and pull guys out of the ditches.....that rig would move anything. They usually expressed their gratitude.....$$$. Don't forget the 332 in the FE series and you might mention that Ford, by putting the 429 into the Mustang, screwed up the exhaust runner in the heads due to the engine having to fit between the shock towers. It makes nearly a complete U-turn....very bad. When I build 460's I ported the exhausts by leading the flow to the top of the port and Devcon-F the lower part of the exhaust in the head.....it's a dead area , anyway and this helped keep the velocity higher in the exhaust and improved scavenging with headers. What I should have done....if I had the money....was go with good aftermarket aluminum heads. I put hours into those damn cast iron heads. I think the DOVE-C heads were the best for the 429/460's. Keep the Faith.

not all small-block Windsors were produced solely at the Ontario plant, but the name stuck with the engine. The 351 Windsor has long been an engine appreciated by enthusiasts for both racing and street cars. In 2006, an enthusiast re-engineered and rebuilt a Windsor 351 to produce 816 horsepower. This was achieved without adding fuel injection, turbo charging or super charging. The name "Windsor" comes from the Ford engine plant in Windsor, Ontario, where the engine was produced between 1962 and 1969, the year in which production was moved to Cleveland, OH. As mentioned earlier, 1969 introduced the 351W engine rated at 250 HP with a 2 barrel and 290 HP with the 4 barrel. The 351W has a taller deck height to increase the stroke. While all 289, 302 and 351 Windsor’s share a 4″ bore, the 351W engine has many changes that set it apart from other Windsor engines. The intake, heads, pushrods, block height, and firing order are just a few of the more notable differences between the 351W and other 4″ bore Windsor engines.

[@livewire2759]

This is why I'm a Chevy guy. Big blocks bolt up exactly the same as the small blocks, same mounts, same bell housing. Yeah, some of the older Chevy engines were different, but they're so rare at this point it doesn't matter. Ford did so many different things, changed shit all the time, nothing matches anything else, it's ridiculous. The only thing Ford engines have in common is that you can get an intake for any Ford engine that works with their good ol' motorcraft 2 bbl. They sure loved that simple little carburetor, they put it on everything for about 30 years or so. Honestly I think those carbs are about the only thing I like about Ford, probably because it's the only thing they ever built that was simple! It makes you wonder why they complicated the hell out of everything else they ever built.

Live Wire - you don't have to Know shit to work on a Chevy. And all you need is a hammer screwdriver and a pair of plyers. But with Ford you have to have functioning braincells and a little bit of automotive experience. Usually Ford guys know what bell housing is needed for s given engine. And if different motor mounts are needed we know where to find them or how to fabricate them. It's really not a problem for us. You Chevy guys are easily confused. So you need to work on something simple that doesn't require much intelligence. Working on Ford engines has never been difficult for me. My dad was a certified Ford mechanic and I started working on engines when I was 14 years old. V8s in line 6 and 4 , small lawnmower engines etc. And yes even gm junk ass engines. And really I haven't worked on very many v6 engines. Except in a Taurus and a 3.1 gm engine in my 95 olds gutless Cierra. That POS gm junk left me stranded on the interstate and so did my 97 gmc Jimmy that's had the wonderful 4.3 vortec engine... another POS gm pile of junk. The only gm car I ever owned that didn't leave me stranded in the middle of nowhere was my '67 Caprice. That's why I don't own any gm shitboxes. They suck and they will leave you stranded. That's why they put that little blue tow truck button in gm cars and trucks. Because even Chevy knows their junk ass cars suck.

On the street the Windsor was the better performer in stock form.The Cleveland could make more hp at higher rpm but you had to put on headers to really make them run. I have had both and I prefer the Windsor overall.I have also built a number of both, and the Cleveland can make a lot of hp.

[@VigilanceTech]

the head to get for the M was the Aussie one with the small intake runners and big valves. Also you can narrow down your mopar slant 6 rod and put in a Cleveland crank with rod and main journal spacers to reduce the parasitic drag on those surfaces. Then you need to have a set of custom hypereutectic pistons made with a short wrist pin height. There was one year (maybe 1974) that had the small bell housing bolt pattern. Also a couple years had tendency to crack in the valley when making big HP so you want to avoid those. Its not too difficult to drill and tap these for 4 bolt main (and I think some of the truck motors had them already). Considering most of the C6's had a fair bit of parasitic losses better power can be delivered to the ground with the C4 (if you can find the one year that will fit the bell housing) or go manual. I believe some of the motor home EOD transmissions will fit the big block bell housing and they can be special built to be pretty decent (but stock they suck)

[@gseitl4337]

to bad the Australian 351 isn't mentioned they had the better heads becouse the Emission regulation doesn't came that early

[@StormCentre88]

Years ago I used to have a 351 Cleveland with 4V (stamped on the) Heads; in Australia. Those intake ports were huge, probably (if not bigger than, then) as big as a BB 454 Chev. Built right those Cleveland engines were awesome, and in my opinion better than Windsors; although I concede Windsors have a stronger USA aftermarket. For the street, the 4V heads were too much and you could build a better engine by swapping out the 4V heads for 2v heads, but then most guys didn’t like to do that because it sounded better to say you had Cleveland 4v heads and let everyone see the “4V” stamp on the head’s corner when the hood was pulled. The Australian Ford GTHO (running a 351 Cleveland with 4V Heads) was the fastest production 4 door sedan in the world there (USA included) for a while there in the 70’s; until (I think) the AMG came along. In Australia - back then - not much came close to that car and particularly that engine. I had quite a few friends that had 351/302 Windsors and Clevelands (some of them also drag raced), and by far the stronger and more reliable engines were the Clevelands. The Winsors would often blow bottom ends and they suffered from volumetric efficiency issues when compared to the breathing (heads) capabilities of the Clevelands. This - in my opinion - was why/how the Boss engines came about.

[@mikejones2200]

Buddies told me that there were a lot of 2 barrel ones in various bodies that were fairly cheap. (way back when) Fords were just as fast as Chevys for the same CI, it just seemed that it took a lot more money to go the same speed. To each his own.

If you are planning on building a 351 M engine the best way to improve it is to add the 400 Crank and you have a factory stroker. The advantage of a 400 is the piston deck height is the same as a 351 Cleveland all that needs to be done is Bush the small end of the rod down to .912 ' to match the Cleveland piston pin.

[@4abetterfuture]

"The advantage of a 400 is the piston deck height is the same as a 351 Cleveland" surely you mean the same as the 351M, since the 351C is an inch lower in deck height than 351M, & 400. I've got an early 400 with an Edelbrock Streetmaster 400 4-Barrel Intake.

GM will let you bolt a 455 Olds to a Turbo 350 trans, but it won't last for a week. I guess their idea was to make several car lines and just us interchangeable parts so you ended up with Pontiacs or Buicks with Chevy motors or vice versa.

I'm not a motor guy in that I can do what you do. But most everything else on the truck I will do myself. I do want to build this engine however and from what I've learned so far your assessment of the 351 modified is correct. And yes the intake manifold is better suited as a boat anchor. I pulled mine off because I suspected I was losing vacuum. And it wasn't just very old gaskets leaking it was a Friday when they cast the manifold. It was very poor. It had been sucking air from day one through holes and pitting. I didn't have the money to start the whole engine build then and was already invested in rebuilding, overhauling the transmission and transfer case etc. So I did a very careful JB weld repair and it runs way better. The idle is steady, I immediately had to back the idle adjustment down. This engine had been sick all it life. I can't wait to get into it and build whatever configuration will work best. I was leaning towards the edelbrock manifold and 4 barrel carb before I watching this video so now building a true 400 is definitely an option.

Their claim was that that setup was considered to be a "StreetBoss". It was a extremely narrow intake compared to any other setup... I have a 351M in a 77LTDII that my Dad bought for me back in the 80's. The cats were cut off and a Dual exhaust system was installed. The engine was very lively with the 2VV TBI and electronic ignition system. We later parked the car, when the emission laws came into effect that it had to pass inspection with the cats. At that time the Cat's pricing went crazy, as many people were scrambling to get their cars legal again. According to your thoughts on this video/topic, seems like that said, Boss setup was bogus.

I appreciate you're honesty. 351w,c,&m. W small block wedge head. C small block canted valve head, open & closed chamber head. M destroked 400 to 351. Done when Cleveland plant shut down to keep up till windsor plant could get up to speed. 351C 2V 4V small port big port respectfully. The oddball 302 Boss, Windsor block cleveand head, water port to intake. Now classes. 302 small block, 351W small block 1 inch taller deck height. 351C/400, 335 family. C same deck as W, 400 1 inch taller Hence the M, 400 destroked to 351. Finally 429/460 385 family. many different heads also. I hope this helps. Fords are hard to absorb as there are so many variations. Thank you for reading, Irie L Bass.

[@michealdavis9884]

Bolt the big Cleveland head on the 302 don't forget to drill and plug the water jackets ,then get a boss 302 intake and it will bolt right on ,it makes a very mean small block that will eat any Chevy of Mopar,

Cleveland 351 was in my 70 Cyclone ...first car that made 100000 I ever owned. most powerful car I owned until 83 460 in PU

[@jgsmith4957]

Dont forget the 69 & 70 BOSS heads .Very hard to come by .Basically ,Cleveland heads with bigger ports and smaller chambers !

[@Sokrates66]

Close but no cigar, real Boss 351 one year only 1971 in -72 they got open chambers, 351c closed chamber heads was cast 1969-1970 but in 1970 vehicles + that the Boss 1971 had same heads with milled pedestals and solid cam.

J G Smith - they were best suited for full race applications that's what they were designed for....

[@phantomwalker8251]

heaps here in aus,or just get 302c heads,.same .

[@jimclarke1108]

I thought i knew everything about the Windsor and Cleveland engines,until now, still cant remember everything iv watched here, great video

[@chrisrye9128]

actually rods were same size center to center in 351m vs 400. piston pin height varied tho. I'd say swap in a 400 crank since u have to buy pistons anyway. my 2 cents

[@ldnwholesale8552]

351C too are the same pin height, just the Clevo has smaller pins.

[@jameswornica8545]

would make for a lighter rotating assembly smaller pins

[@stephanM5]

The Windsor engine was not manufactured in Windsor Michigan but rather Windsor Ontario which is located on the other side of the Detroit River in Canada.

[@EPstroker]

I'm sure this motor is already done by now.....but, the difference in a 351m and a 400 is crank and pistons. rods are the same. IMO id always use a 400 crank in these particular 335 series motors. Why not, a simple factory crank swap buys you an easy 50 cubes.......with some good heads and pistons, along with a good cam and non factory retarded timing set. 50 more cubes is a big performance potential. the 400 can be a great sleeper motor with the right parts on it.

[@gijo5088]

yep. The 351m i had in my truck out performed the 351c 4x4's hands down.. some performance guys down talk the 351m and call it a truck motor.. well from my experience I would rather have that truck motor cause it had gobs of torque.. for chevy guys this would be the difference in the 2 bolt main and 4 bolt main 350.. of course you want that 4bolt main!

[@billbeyer657]

I took a 351M block & rods and put 351C 2V heads and a 400 crank with flat top 400 pistons and built a monster torque motor. Had over 500 hp and 600 plus lb/ft of torque. Came in at 2500 rpm and stayed flat to 5 grand. Stuffed it in a 78 Bronco. It was a beast.

[@billbeyer657]

fitty6pickemup no a 351M is 351 ci. A 400 is 400 ci hence the name. Yes they do share the same block. Also the 400 came out before the 351M so it’s really a modified 400.

[@cclcanadiancountrylife3628]

Just want to say Very good and informational video. Thank you. Got a question tho, I’m about to rebuild a 1985 Ford 3.8L 232 engine and I found a article that stated a 232 is actually a baby Cleveland they are identical just minus 2 cylinders. Have you had any experience with the 232 or if it is the same as a Cleveland?

[@pokebass1]

Hey man, I have a 4 barrel 351M/400 intake. They do exist.

[@Myvintageiron7512]

O Wow that's cool I was not aware of that Thanks

[@scdevon]

Hold onto that. It's a rare piece. It's most likely off of a police package car. Late 70's Ford LTD II police car maybe.

[@fitteritout3622]

pokebass1 I had one of my dad's friends give me two 351m engines that he built for his oval car because supposedly he found a better option for his race car they both had 4 barrel I think holly brand intakes and tuned carbs I still don't know how or why he just gave them to me to get them out of his "way " I put one in my 81 short wide and scared the crap out of myself so there are intakes out there to be had good luck finding one

[@warrentrucks09]

They were not that rare, I had a 79 F150 ex-cab. It had a 400M with a 4bbl carb and Automatic tranny from the factory.

[@jonnightrain]

Got a couple of exhaust manifolds, that would not fit my 351c. They are the modified, a C6 that must be for the modified block... Boat anchors. ..

[@northboundbros5666]

I have a 400m in my 1979 F-250 Ranger Highboy, There a great truck engine. There a torque monster done I read some one put 340 Dodge pistons and 350 Chevy connecting rods in a 400m, they got 505 horse power and 640 torque out of it. They would got more if they made better performance intakes for the 400m but the only make good truck intakes for it. You could prob make an high rise intake for it some look easy to make then others.

[@johnt9906]

77 was the last year for the highboy. 77.5 - 79 F250's were NOT highboys.

[@damonlemasters3424]

Junk they are good boat anchors tho I had quite a few of them hard on gas barely enough power to get out of its own way and they loose oil pressure. Throw it away and get a 460.

[@cameronboyce4695]

Years ago my dad had a 79 F150 with the 351M. He did the same thing, threw a 400 crank in it and it ran good. This was back before you could just jump on the computer and order stroker kits and parts from places like summit too.

[@amyhepker9025]

I had a set of FORD 351 Windsor heads on my 289, !966 Mustang, the Desirable C9OE 4 Barrel Casting that had Larger Valves the 1.84" Intake Valves Valves and Larger Intake Passages. It added approximately 40 HP over the Stock 289 heads. The Combustion chamber was open unlike the 289, but the added size of the Intake Ports and Valves helped that much.

[@Myvintageiron7512]

yea really good heads the gy40 heads are similar

[@lelandlewis7207]

@@Myvintageiron7512 , I forget the years, but there were trucks with GT40 equivalent heads. Everyone in the middle 2000s was looking for them for their 'stangs.

[@kennethcohagen9037]

Ok, I'll try this again. In order of performance potential, worst to best... 351Windsor 2bbl, 351 W 4 BBL(had slightly larger ports), 351Cleveland/Modified 2bbl (canted valve head similar to the Cleveland design) 352 FE ( used the same basic head as the 360,390, and larger low riser heads), Boss 302-351Cleveland 4bbl heads. Port volumes increased the higher you went on this list. Below the 351W 2BBl was the 289/302 heads which worked ok for their small displacement. The Boss 302 was used for Trans Am racing and had huge intake ports that you could about put your whole fist into. They were as large as a Big Block Chevy square port head. It had canted ports and flowed like mad! The 352FE was an early truck engine. The FE was used all the way up to the 428 and 427 side oiler performance engines. With aluminum heads they were as light as a Small Block Chev, with tons more hp! The Cleveland bottom is weaker than the 351 Windsor bottom end. 351 modified blocks have a higher deck height which give you the possibility of some really long rods which will help make power. But still have the same problems as the 351C, which was weaker and had oil delivery problems. Any one of these engines can performe, you just have to pay attention to each designs weaknesses and modify the block to overcome those weaknesses. I built a 351C that ran 8.72 in the quarter mile.

[@markgodfrey790]

Kenneth Cohagen- you are mostly right...351 c biggest problems we're a weaker bottom end and oiling problems. The 351 m had a beefier bottom end but I don't think they had the oiling problems the 351 c had.

[@Sokrates66]

Some miss information in that post, 351w 2 and 4bbl has the same valves. Boss 302 and boss 351 have the same port volume also the early 351c-4v had the same heads.

Years ago my wife had a 77 T-Bird with a 351MC (modified cleveland).If you needed a part for that engine you had to be sure you took the old part to the store with you and match them up perfectly.The parts manuals never seemed to match up with what I needed.It seemed like there was always 6 ,7 or 8 choices for a lot of parts.Found out the hard way. Wisdom comes with age and failure I guess.Always take the old parts with you.

460 C6 is what I replaced my 351M with. Easy swap, you can use the same radiator. shorten the drive shaft for the C6, easy and cheap.Use 72 up Torino 429 engine mounts, set the engine in and level it, drill holes for new mounts and do up the bolts.
