Interesting results! That 363 had really big heads and cam, too bad the induction system seemed to hold it back so much. Took a couple “extra” lbs of boost to make double the NA hp. The bored and stroked 351 was amazing, little heads and little cam to make very respectable NA power. Another great video, lots of info. Thanks Richard!

Brian Dugle : The Box R is a T3 Tickford style intake. Normal Showa G52 intakes on the SVT and Lightenings drop out well before 425 hp gross. The Box R needs a few nights veolocity probing with a good SuperFlow flowbench. Radius work on the edges helps. Anyway, the LS has replaced the Winsdosr derived 351 to 427 stokers, but that 363 is shallow and compact in the way a Modular or LS or 427 siamese bore Fraud can never be. 363 with a HOT concept... High Output Turbos! 427= LPT Low Pressure Turbo. But I still like 9.469 to 9.500 inch decks too. Spoiled fer choice, Young Skywalkers...dont waste a shot....

[@deanstevenson6527]

Brian Dugle : I love production cast iron blocks that dont split when making 1000 hp. Ill bet a DZ Small Block Chevy 302 wont. But Im sure a stroked 5.0 will. Richard showed us that awesome TFS headed turbo F150 5.8 truck engine....it was the special low compression engine he did. It ended up making 1000 hp but, ahem, became junk due to rods, maybee not the block. I have pictures of his smiley face at Four Eyed Pride suggesting some stronger rods before his dyno run blew it up. The modern 82 mm throttle intake upgrade happened in 2001 when Ford Australia made a factory 342 stroker with a kind of Box R upper and lower EFi, the 335 hp net and 369 lb ft T3 Pursuit 250 engine. They reverted to GT40 P iron heads after about 1500 aluminum head Y303 or whatever factory 295 hp 5.0 OHV engines were made. Id say Ford were aware of how little extra strength in reserve existed in the factory 5.0 iron block. Even the 289 Le Mans GT40 Mark II' s with quad Webers making 380 hp gross had a few issues surviving. The race 8.2 inch deck 4.125 siamese block is really nice. Unlike GM, Ford didnt like giving 65 pounds of block iron away for free with every engine. Back to Richard. Love this channel.

[@mjcmustang]

Well boost pressure is a measure of resistance, so ideally, an engine that can make more power with less boost is more efficient and less stressful on the engine itself

[@jeremypike9153]

Boost isn't necessarily a measure of resistance. For example boosted engines generally use more lift in a camshaft to increase airflow. The reason being because boosted engines aren't as efficient when a camshaft using "overlap" is installed. Valve overlap in a N/A motor uses exhaust pulses to scavenge airflow across the cylinder but in a boosted application just allows air to freely flow out the exhaust manifold requiring a bigger turbo or supercharger to acquire the same cylinder pressures as if using a high lift camshaft instead of a camshaft with lots of valve overlap.

[@mjcmustang]

@@jeremypike9153 so when you increase the valve duration and lift you're reducing resistance to flow? Thanks :)

[@jeremypike9153]

@@mjcmustang You most definitely are reducing the resistance to flow if valve overlap is involved in a "boosted" application only. Overlap hangs both the intake and exhaust valves open for a split second relying on the firing order of the engines other cylinders to help pull air into the combustion chamber which increases power in a naturally aspirated engine but not in a boosted application. True boosted camshafts will have very little valve overlap if any. The reason is that the extra pressure coming into the intake from a supercharger or turbocharger you want to stay in the cylinder for the piston to compress yet again. If the exhaust valve has overlap with the intake valve the pressure from boost blows straight out of the exhaust requiring more pressure to over come the "boost leak" that was created by valve overlap. The concept of boost is to "technically raise" atmospheric pressure mechanically of course. The more pressure you have in the cylinder before it compresses the more the air is compressed during the compression stroke.

[@jeremypike9153]

Most aftermarket camshafts with extra duration & overlap also have extra valve lift which is why they increase power output compared to an OE camshaft but if overlap is eliminated in a boosted application cylinder pressures are increased resulting in more power than a camshaft comparable with extra valve overlap.

[@jeremypike9153]

Duration as defined is the amount of time the intake valve is opened as a measurement and the amount of time the exhaust valve is opened as a measurement. Valve lift is how far each valve is opened. Overlap is the amount of time each valve is open at the same time. All of these except for lift are measured in degrees of rotation. Lift itself is measured (at the can lobe itself) how far it transmits the valve train. Lift can be changed on an OE camshaft with different ratio rocker arms or the change of the pivot point on the rocker arm. Duration and overlap are not changeable without changing the shape of the camshaft lobe itself. Most of the time an aftermarket camshaft or set of camshafts (depending on the engine) will come with a card explaining the measurements of at least two of these measurements lift and duration overlap can be mathematically figured if not given on a cam card.

My hope is that it will work well enough to produce at the very least 450hp. I will upgrade to a second 6466 precision turbo if this works when I swap to a Dart block, forged crank, nastier cam and larger injectors. Everything I built except for the crank, cam and injectors should be able to swap over to the Dart block when the time comes. After those upgrades I will be uping the rpm rang of the engine significantly (med to high 7000s maybe more) and hopeing for at least 1100hp..

That means before the test even started the engine had already been at wot for almost five seconds. All the extra plumbing and issues that maybe come from a remote mount are basically outright ignored with a brake dyno. Even the difference in exhaust pipe charge time is over 0.1 sec when you put longtubes on a car as compared to cast manifolds, you will never see that on an engine dyno but you will probably notice on a road course.

Oof bro. Even the cheapest speedmaster blocks they rate at 1500+hp. Your looking at getting a crazy expensive bottom end, like one that won't break until 2500hp and giving it enough airflow just to break it. With the thicker cylinder walls and splayed billet caps there is nothing that sticks out as a weakness and as long as the deck is done right you will have to do something incredibly stupid to break the block. Even to get the power to split a Gen1 race block requires splayed valves, methanol and huge boost or aluminum rods and nitro. It's not a billet dry block so if you treat it like a top fuel engine, the block will probably let go first... But why would you want to? Most of the failures on the blocks I've read about are stripped threads in alloy blocks, and to be fair they're not helicoiled and probably should be. The machining is crap and there are numerous issues with deck warping in race applications and sleeves coming loose when at temperature. Still, how hard do you think you would have to hit it to split the block or push the mains out?

A general "add ring gap question". Do you re use the existing rod bearings ?? Might sound like a dumb Q, sorry if so :-).

[@mitchthompson6619]

Would you be able to run a turbo on pump fuel on a windsor with 12 to 1 compression? If so video would be cool

[@richardholdener1727]

on pump e85 yes-otherwise not a good idea

[@mitchthompson6619]

Cheers mate

[@michaelangelo8001]

I wouldn't want a .700+ lift cam in a street engine, I know that much. But you can never go wrong with more cubic inches. Keep it mild enough to survive and be drivable... then add whatever amount of boost is required.

[@MoctezumasRevenge1]

Say you find a junkyard 351, and you refresh it to OE specs on the short block but add ring gap. How should you go on the bottom end? Is it a limit of horsepower or is it a limit of boost?

[@AlbertaRednecks]

I'm with you love them both

[@erenzoscroggins8056]

I'm not a Ford guy at all... But when it comes to boost I'm for it.. A lil bit hahahaha💪🏾💪🏾💪🏾 good work Rich

[@kennybiggs3944]

I hate to be a broken record but I’d like to see the smaller engines make power such as the Chevrolet 283 and Ford 289 it would be even cooler to see a Pontiac 301 With boost 283 would be awesome

[@BucksSuperStereoWorld]

I would really like to get a first gen Mustang, take a HiPo 289, swap in forged rods and pistons, some big port aftermarket aluminum heads, a roller rocker turbo cam, dual valve springs with titanium retainers, 1.6 roller rockers, a big single plane tunnel ram intake, head studs, some MLS head gaskets, a multi-port fuel injection system with return, a big 100mm throttle body, a set of 2200cc injectors, two GTX3582R Garretts, a full QA1 coilover suspension and tubular control arm upgrade, and not just drag race it, but also road race it because it'll handle.

Just a few words: Twin-turbo 351 Windsor w/Cleveland Boss heads. ;)

[@woodchuck5277]

YES, A Cleveland. that would really scare off the LS guys!!!

[@timothybayliss6680]

Why? Factory Cleveland heads cost a small fortune and suck compared to almost every aftermarket casting that exists. Then you add in all the one off pieces, even if they are common today, and what do you get? You can buy a set of Chinese castings ready to bolt on for less than $1000, if your gonna go all Kung Fu swapping to Cleveland valve angles, try to get a Yates head. The factory iron castings are heavy, old and would cost more to buy bare than a complete aluminum set that might not outflow them at 600 lift, but weigh 60lbs less and have way more compatability with factory parts. As opposed to swapping a whole bunch of stuff to get a fifty year old head to work, why wouldn't you just invest half the money to get a Windsor head that outflows it?

[@woodchuck5277]

@@timothybayliss6680 Why? Cause Cleveland heads are without a doubt the best small block head ever produced. All the fastest small block Fords use Cleveland style heads. If your on a budget the cast iron head will make great power, if your have don't have a budget then yes buy aftermarket heads. For all out max power, any head will cost a fortune, it all comes down to how fast your pocket book is!

[@Zekais]

@@timothybayliss6680 "Windsor head that outflows it..." Yeah, I would really love to see an inline valve head outflow an equivalent level canted valve head. Whatever inline valve head you choose and whatever you do with it, it's going to face some mountains it can't climb. Mountains named Blue Thunder and T-Rex. I can't recall any inline valve headed Ford winning the focused competition at Engine Masters. I do know Cleveland headed entries won a number of times, that's why Wood Chuck intimated that LS boys would be worried by a canted valve Ford more than they would by the more pedestrian type. Canted valve Fords have made a pretty regular habit of kicking LS ass in EMC, not counting any other venues. I've currently got 1 Cleveland, 1 B302 and 3 Clevors. I admit, it is hard to come up with the intake I prefer for the B302. The others? No parts compatability issues at all. B302 and 1 302 Clevor (2v heads) run 50 year old iron heads, alright, but 351C, 302 Clevor (4V) and 351 Clevor all run aftermarket aluminum heads, priced better or at least competitively with inline valve Ford heads.

sooooo, many choices i’m in the process of building a 351w and i want a comfortable 500 hp at the flywheel would y’all stroke it or leave the OE crank

[@aaronrepsher7628]

I think this is a great informative video as I'm a foxbody owner and enjoy seeing options for more powa, but going 427 is a very pricey option and I've been leaning towards the 351W base and stroke it to the 408 or 416 with boost!! With that being said, Richard what is a safe reliable HP number and Boost pressure to pump out of a stock block 351W while being reliable and having good longevity from this type of setup?(I built a 306 and am planning on running my vortech with about 10-12 PSI and methanol injection for cooling of IATs and reliability BUT this setup is only temporarily until I build a 351 based engine and I want to go turbo and methanol injection with that setup)

[@richardholdener1727]

you don't need a 408 with boost

[@aaronrepsher7628]

@@richardholdener1727 so you're saying I could build reliable 800-1000 on a 351W built around a proper cam with the supporting mods ie. Springs, heads, intake and of course the trusty "ring gap" and a turbo to meet that goal? What turbo or turbos would you suggest? Which cam, heads and intake would you also build the 351 with? Also is the factory 351W bottom end going to support everything or do I need an upgraded cranks, rods etc.??

Huh! Perfect timing. I'm trying to plan out my motor build and deciding what cam has been a massive brain killer. Did you need to run different push rods and did you need to do anything with the cabs to make them run with boost? I have heard that the carb will starve of fuel so was thinking about the sniper EFI system. Thanks for doing these tests btw!!

pushrod length needs to be measured and the carb run on the turbo motor was a dedicated blow-through carb from CVSU
