It's a 5000rpm truck motor! It doesn't bolt to the small block bell housing. There are aftermarket intakes, but they fit the smaller ports in the factory heads with no quench! It works great in a truck used for towing and fuel economy was fair considering the application. While I guess you could put a set of Cleveland heads on, the intake manifold has smaller ports than the head. It's nearly 100lbs lighter than a 460, but a stroked Windsor is 100+pounds lighter, smaller, and parts are falling outta the sky if you stand in the right place! A 408 is lghtyears better, externally lighter, and parts are readily available! The even made 460 swaps obsolete!! I know some guys that ran a 400 till they got the 460 back together, it did OK, but Hot Rod magazine wasn't there taking pictures!! Put the 400 into an old f150 and use it to pull ur car to the track, you'll be satisfied that way!!

I continue to love watching your dyno tests and lives, the information you give is a credit to your professional approach. 5:48 Stock, the 400 M had a tiny carb, with about 9" of Hg Vaccum at WOT with a 368 CFM Motorcraft or 424 CFM 2bbl Autolite. It never got a 500 CFM 4412 Holley that you tested it with. Ford rated the first year 400 M as 265 HP gross stock, but you got 267 HP gross. The FE was rated at around 270 HP gross, so Ford had to make the 1971 debut 400 engine stronger than the 12 year old thoroughbred. Our Australian 351 C gave 171 hp net stock with a stock 2bbl (rated 250 hp gross) and 216 hp net stock (Rated 290 HP gross) with a ThermoQuad. Just a 1978 pre production spec 4bbl iron intake with a Carter ThermoQuad adds 63 hp net on a stock 400 M, making 232 hp net, and drops the WOT vacuum to under 1.5" Hg. The stock 2bbl carbs restrict the 400 M to such a huge degree , it's like the world's most Factory Restrictor plate you can imagine. Exactly like a 250 in line six with a Single Carter YFA carb, 175 cubic inches per inch of carb Venturi on each engine. Adding a carb with 85 cubic inches of engine per 1 sq in of carb Venturi adds exactly 63 HP on a 102 hp net engine. Try it yourself next time you test. You never saw a similar improvement with the 292 Chevy engine when it went from 1bbl to 2bbl because of the points and the cam duration qas very mild. On the other channels guys who did the 300 six with the 1bbl carb saw a huge gain with the 2bbl, a 75 hp gain with a 625 cfm 4bbl verses the big YFA Carter 1 bbl. The 400 M is exactly the same case..

There's one huge problem with the 400meh that your are missing. In talking about torque being key to a fun motor in a big vehicle, I completely agree. But there's three numbers that completely invalidate the 400, 460. If you have the room, there's nothing the 400 does that the 460 doesn't do better. It is heavier, and a little bigger, but if you have the room, they are cheaper, there's more support, STROKER! There was just no need to go down in cubic inches and up in money. You have proved time and time again that it's size and set up that matter. So you already have the 351W if you need smaller packaging. Why bother with 400morphodite.

Ill never forget a story in one of the car magazines… perhaps Hot Rod … and they decided to build a 400 Ford, to show what could be done. Back then, dynos were a lot harder to come by, so the only available one near them was at a Porsche dealership. The Porsche people laughed at the anemic numbers from the bone stock motor. The team then threw all the typical upgrades on, the best of what was available at the time (some time in the late 80s I believe), and took it back to the Porsche dealership to dyno it. The Porsche people were rather miffed that, for a pittance (compared to building a Porsche engine), they had increased power to WELL over 400hp. Lol If I remember right (and please correct me if Im wrong), for those who dont know … after deleting the 351C from their lineup, Ford realized there was still a demand for another engine that size. Rather than re-introdcing the 351C, they noted the journal size between the 351W and 400 were the same, so the 351M was created by putting a 351W crank in a 400. Therefore, a cheap way to increase your displacement is to swipe a rotating assembly from a 400, and install it in your W or M block. I cant remember if rod length needs to be adjusted in a W block, requiring shorter rods, but if you have a 351C, Journal and rod size would def have to be reduced for use in a 351C block, however, youd have to ensure that the crank is in good enough shape to remove that much material.

@Cam montreuil engines you can get the same power from those heads using 351c heads, or just deck the ones that came with it and port them. Its that easy. You are old and stuck in your ways.

The 400M was not exactly a "400 inch Cleveland stroker". It was a 351C block with a 1/2" taller deck and 1/2" longer stroke (it actually displaced 402 cubic inches). The 351C heads will fit the 400M, but the intake manifolds are not interchangeable because the 400M has a taller deck, making the intake wider. The Cleveland had far superior closed chamber heads compared to the open chamber 400M heads. Swapping to Cleveland heads would vastly improve the 400M's power.

I remember reading something about Ford considering offering a 4V 400 for the mid-late 70s. Might have been in step with other rumors that the 400 was supposed to replace the 460 in at least big passenger car application. That obviously went no where, but might have given at least some extra kick. I had some passing association with 400 powered LTD II police package cars. They weren’t exactly known for being blazing fast. Didn’t really even seem to have much advantage over the 1979-80 351W Panther platform LTDs. Those were just bad days across the board for the while industry. A 400 4 barrel single exhaust Plymouth Satellite police with bubble gum machine bar only had a top end of around 110-115. I never had a 400 but some high school classmates who did claimed that they did pretty decent on gas in their Torinos. I think that for normal cruising, a 400 likely was more efficient than a 351M in a heavy car. I like seeing what a 400 would really do when the potential is explored. I vaguely remember advertisements suggesting that 4V intakes were available for the 400 back in the 80s, but don’t know anyone who actually bought or installed one. I do remember seeing the Edelbrock SP2P two barrel intake for smog motor operators who wanted a little bit more but wanted avoid the alleged federal prosecution rumored at the time for tampering.

My Dad and I rebuilt the 351M he had in a 1979 F-150. It had a great sound and decent power but for some reason it wouldn't keep good oil pressure when warm. Dad put an oil cooler on it and that still didn't help. Not sure exactly what happened to the engine but I know it didn't last like the 302 we had rebuilt prior to that. Maybe the machine shop dropped the ball on cleaning the block or maybe that's just the way the engine is I'm not sure.

[@markmccarty9793]

Just make the jump to a 460. It'll bolt right up to same transmission as the 400, 60 more cubic inches. Swap kits are readily available, and the 400 oiling problems won't be there! The 460 works really good in truck or big car applications. The 400s inhearented the oiling system problems from the Cleveland, plus that heavy crankshaft hinders high rpm capacity! They just aren't good high performance motors and the 460 does a better job! Plus you have the option of 514 or 521 stroker kits!
