THE OTHER GUYS-400M POWER!!

FULL RESULTS-400M FORD-DO ALUM HEADS, CAM, INTAKES WORK?
Can You Really Make Power from the OTHER Ford-the unloved 400M? Is it really a POS, or is it actually a 400-inch, Stroker Cleveland in Disguise? We ran it stock after a rebuild (don't judge), then tried two different roller cams, ported alum 4V Heads and single and dual-plane intakes (with spacers). All Hail the mighty 400M!

[@cougarfarmer]

As a life long Cleveland guy, I can't tell you how many times I turned down FREE 351M/400 engines. It makes me sick to think about it. T Meyer has been building stroker versions of this engines. Also, Jon Kaase was banned from running these engines in the Engine Master competition because he murders the other guys with them. He made diesel like torque with the Ford 400. Hot Rod magazine built one to zero deck height with MOPAR 340 pistons and other parts in an article called "The Mutt" They made over 500 lb/ft of torque and 500hp. Great video, keep them coming.

[@fenatic7484]

I don’t know if they have an EMC , when they ran vintage one day and LS the next, Kasse brought a 427 Chevy with rectangle port heads 68 was the cut off, but the winner was a 400 ci FE with a set of C4AEG heads that looked suspiciously 😆 like mine that disappeared, but it could have been 👽or 🐿 who knows, but he won on points, their formula, he made 596 hp and 517 ft lbs and it beat all of the vintage engines including the 427 BBC Jon Kaase brought. I suppose the FE won’t be back because the heads are too much like the LS the CSA choke and bowl cc is the same as the LS3. You have to work the SSR and the intake since the manifold is 1/3 or more of the head and the pushrods go through the intake. 1.4 is what you need, some manifolds can’t do it. And you have to work one one side for each mirror direction you have two intake ports angling forward and the rear pair angling back. It works with the POS and TW because the carry nice rounded curves that way. Physics and a lot of modeling.

I built a 400M back in 1975. My parents gave me their 73 LTD, so me and my buddies started competing Ford, vs, Chevy, vs. Olds.

Agree with you to a large degree, Ford's Cleveland engine architecture had the misfortune of coming out on the eve of emissions controls and fuel economy concerns.

[@danielwilson6665]

Konner Kramer , the factory iron block will handle the 434 stroker kit without difficulty. An aftermarket block becomes more of a requirement when the power levels start to reach the four digit level. The price of the stroker kit with options like forged pistons, ARP bolts and studs, H-beam rods and internal balancing is around $2700. I agree with you about taking the OEM parts and preparing them for serious usage. But I wouldn’t expect too much from the stock cast pistons or the 400 rods. The stock crankshafts in the 351-C and 400 are both pretty stout pieces but they don’t interchange between the two engines because of different main bearing sizes. Building for big power using production components is definitely the cost effective approach but it’s kinda like living on borrowed time. You never know when the next time you hammer it will be the last 😳🙀🥺.

I had two of those 400s one of my first car a 1974 LTD, and the second one was a 1978 Mercury cougar XR7, they have plenty of torque for Street driving but there were week on horsepower range definitely but, the thing I loved about them is they were deadly reliable!, Both of those cars they both went over 300,000 miles with no problem only change the radiator in each one at one time and that was it and the first one left me stranded one time and that will due to a burned battery terminal the other one never left me stranded, respectively I drove the first one for 13 years and a second one for 11 years so as far as reliability I give them 10 thumbs up. Definitely wish that they had a experimented with them and made something cool out of them.

[@tinman7065]

My mom had a 1976 Tbird with a 351M. She beat the living Jesus out of that thing for almost a decade and it NEVER broke. Rod stroke ratio was insanely high, so I guess there was almost no side loading on the pistons, cylinders etc. Veryy underrated motor.

[@timothybayliss6680]

Richard the easiest way to fit an aftermarket rod is to use a bbc rod and offset grind the crank for more stroke. Bbc uses a 2.2" rod bearing and 335 series uses 2.311". You can offset grind the crank to 4.2" stroke and bump it some more. I know this is lots of work but 6.635 bbc rods are cheap and close to what you want, you have to either narrow the rod and bearing or grind the crank wider as well. Rebush the big end and your set. Just keep in mind factory 351w cranks fit. You could always use the odd 4.17 crank with 6.2 rods and a custom piston. Edit... A 4.25 crank, that is available, and 6.25" rods, that are available work perfect with a factory 351m piston after. 008 is taken off the deck. There is options. 4.17" cranks are avaliable and with a 6.3" rod this works with it being a little above the deck, as long as your gaskets are atleast .045" thick you'll be good.

[@billdang3953]

Nice to see that some people are exploring the potential of Ford's forgotten tall deck Cleveland engine. We had a 73 LTD station wagon with a 400 and I always thought that it was a gas hog and a slug (in retrospect this was mostly due to vehicle weight and the use of tall gears more suitable for steady speed freeway cruising). Examining the 400 in closer detail of late, it came with basically 2V Cleveland heads. If you look at the combustion chamber shape and valve layout of the Cleveland heads, the look remarkably like the Mopar polysphere heads that they used on the pre 1966 318's. We also used to have a 1966 Dodge which used a 318 polyshere and I remembered haw that engine really hauled. It therefore stands to reason that the Ford 400 can be built to the power levels shown in this video. Was a bit surprised to see how low the horsepower was as shipped from the factory. Most 2.5 L 4 cylinder engines from the likes of Nissan, Subaru, Toyota, eat. easily get more.

[@dennislisahirschauer571]

A long time ago I seriously built a 351m for a 78 bronco. It made stupid power. Enough to break everything but the built c6 trans. So I know for a fact that these engines are no joke. Great video!

[@stuffandjunkandthings364]

Man, do I have some stories from these engines. I had a slew of them in my misspent youth. I had a good set of 4v cleveland heads on one (the spacers were, at one time, off the shelf) that I had an aluminum dual plane intake on, topped with a 2150 motorcraft. Lumpy solid lifter cam, and before you laugh at the 2bbl setup- ask yourself "who says all of the air fuel mix has to come in though the top? The tall deck height (and 385 series bellhousing pattern) meant that there was a lot of unused real estate between the top of the ring gear and the top of the bellhousing- enough for a sizeable fuel line, and accompanying nitrous line. Yep, I plumbed the nitrous and fuel through the back of the block, and under the intake. Also installed a couple of toyota vacuum switching valves on fittings down there too (kill two cylinders 5&8 if I remember correctly- to hide the cam at idle, and with it pulling the air from the valley, it'd usually smoke like a freight train too). I think the best it did on the motor was 303 or 304 to the wheels on the motor, and a little short of 500 on the bottle. Stock bottom end, all junk. Methyl Alcohol for the excess fuel when using the bottle (fuel tank was in the trunk) When it would let go, just go get another one, swap the cam and top end, drill a few holes and go back at it- And before you ask, yes those modifications (see also: butchery) did make it leak oil. a lot of oil, actually, nut they usually didn't last long enough to worry about that. Especially after I modified the stock egr plate from a bronco with a spray bar, and rigged up a pump to run model engine fuel (90% nitro) into the engine. Life span was about 3 passes that way lol. I had another one I went the other way with. Stock bottom end (forged pistons), and like you was irritated with the inability to get the compression ratio up to where I wanted. So I put Windsor heads on it. Other than opening up the heads for the larger head bolts- they went right on. The compression ratio went from meh to ridiculous, so I was running race gas in that one. Insert large hydraulic roller cam (don't recall the specs, its been about 20yrs), and proceed to absolutely butcher not one, not two, but three performer rpm 351w intake manifolds. A lot of tig welding later, along with some foul language, and the end result was slightly better- 370 to the wheels. on race gas. In retrospect swapping it out would've been cheaper, easier, and much faster (in every sense of the word), but as the patron saint of automotive lost causes, I HAD to build it that way. Anyway, Love the videos. Do a dodge 4.7 one day

Mike Taylor actually you can use any Pontiac head that had small valves or there was a older edelbrock head that had valves that barely cleared it but did so yes there are heads to flow and then you can also use a normal aftermarket intake ( I wouldn’t recommend it for a normal street car but it can be done and has been done)

Your initial 265 H.P. was really close to the rated 260 H.P. on a 1970 LTD 400M engine. I don't know the torque on it but I was amazed with it in my 1968 Ford F-100 Ranger. Coupled to a FMX transmission and a 410 limited slip differential, it was a real surprise for a stock 2V engine . It seemed not to notice if the truck was empty or fully loaded.

It did however have the towing and heavy duty package.... extra large gas tank....big rad....C6 with 9 inch rear....big sway bars. It did have leather seats. It was actually ordered as "catalyst delete" I still have the original papers. Fun car to drive...lots of torque easily made the Bird bird go. People put down the 400 but I thought it was great ! Cleveland 2barrel heads.....long rod engine smooth and gobs of low end torque. It was however thirsty......you needed that big tank. It was 15 years old when I sold it and still purring like a kitten. Wish now l'd kept it ...black ...red leather...alloy turbine wheels....full dual exhaust... Lots of power and a joy to drive :)

[@jimmiller4667]

I ran clevelands in stock cars for years. When I first got hold of a 400 I made my own spacers and ran Cleveland intakes and cams, very very strong engine. The issue is piston and rod selection. Not sure how you got it to live at 6500 but maybe it's because it was only a short time on the Dyno. I kept mine to 5500 max and still chucked some rods out of a couple. The last one in a mud truck, my cousin borrowed it and while screaming it on the power line threw a rod and then drove it back home. No oil, rod crashing around, just as he hit the yard another came out and almost sawed the engine in half. It only quit when he took his foot off the gas. I found out a couple days later and have never let him drive anything of mine since. Good motors, bad rap.

I played with several carbs settling on a 3310 with a massive long duration accelerator pump, and light spring in the secondary diaphragm. The stock 2.43 rear gears had to go. I found a donor 3.50 3rd member from a van. Brutal torque. Passing people on long steep hills while towing the boat brought joy that overcame the cost of the fuel required to do so. The sound of the secondary's slamming open with virtually unlimited fuel flow brought a smile to my face and many interesting looks from the people I was passing. Torque is good. I don't think mine ever went over 5700 RPM if that, 5200 was enough.

Another great video. I had a 400 in a 75 F-250 and it was a good (for the day) low end grunt motor. Ran out of breath before 5000 rpm’s stock. I first put dual exhaust with “turbo” mufflers and that woke it up a little. I decided to get the heads freshened up because it smoked a lot when you first started it warm and got a lot of 💩for it from my Chevy buddies. I was a kid fresh out of vo-tech at the time and didn’t realize I could have just put in new stem seals. I had a 3angle valve job done and when I got them back I gasket matched the heads,intake and the cast iron exhaust manifolds. I learned that in vo-tech from the engine teacher who said if you have a lot of time and no money get the die grinder out and match all of the ports(with the gasket holes)and you can gain a little bit of power and not spend money. Same applies today especially on older engines… newer ones are port matched better today but you can still gain something making sure the ports are as big as the gasket holes. Just be careful not to get crazy and make holes too big and burn through a coolant passage or another place you don’t want a hole. Cheap h.p. for very little $$,if you have a die grinder and patience. 👍🏻. BTW I could waste any of my buddies 350-400 small block Chevy even when it was stock and after the mods only the guy with the 402 big block Chevy could keep up with me on the road or trail.
