What is your source for the 351M/400 is a Medium block engine. Every thing I have ever read said it is a small block.

I can't be total sure I was 3 when this motor went out of production.
Here is another good artical about the 351M/400 By By David Resch

the block was designed off the big blocks and the internals off the 351 small blocks.....the bell housing off a small block wouldnt fit the 351M/400....

The Boss 302 heads are the predecessor to the 351C 4V heads. Only significant differences are the water passages and combustion chamber size.

My point was a 351C and Windsor engine share the same bore and cylinder spacing. All to clarify the 351C as a small block. It just has larger proportions up front and with the heads / intake.
I wasn't trying to be an *** about it. I was just stating that there are many differences between the Boss 302 and Windsor 302 block, Just like you stated. Externally they may be very similar, but internally they are modestly different. And also that the Boss 302 is not just Cleveland heads on a 302. As you said the Boss 302 heads were the predecessor to Cleveland 4V heads, that doesn't make them identical. The only identical part about them was the polyangle wedge combustion chamber and staggered valves.

The larger proportions up front and up top of the Cleveland is why I really think a Cleveland in a Ranger is a bad idea. A windsor 302 is really cramped in the front on most Ranger 302 swaps, Why do you think most swap mounts set the motor back a little? If a 302 is cramped, how cramped do you think the Cleveland? I know a torch and a welder can fix anything, but it isn't always pretty.

It was hard to tell if you were trying to argue with me, or what you meant by your post, but you said almost the same thing I had said but with different wording and it was mildly confusing.

Ford never made a small, middle or big block engine. the term small and big block was coined by GM and stuck as a marketing and media term.

Ford had five (excluding the modular and flatties) series of v-8 engines; Y-block, FE (designed off the y-block), Windsor, 335 and 385 series.

221, 260, 289, 302, 351, 300, 240, 351C and some 400s carried the "small block" bell housing pattern. 370, 429, 460, 400/351M (there was no 400M, just 400) carry the "big block" bell housing pattern. that is the only i ever refer to them as a "small or big block".

the 351C began production in LATE 1969 and ended in 1974. the 400/351M started in 1973 and ended in 1982. the 351C is also seen as more of a performance engine and the 400/351M was more of a work horse/torquer engine. the reason the 400/351M 385 was to replace the "aging" FE series in the cars and trucks to meet the stricter emmisions standards. most 400/351Ms get a bad rap because of the horrible add on and built in emmision control devices. (personally i love the FE engines, LOL). then the 400/351M was dropped in favor of the 351W because they couldnt get it to meet the current (for the day) emmision standards. the 460 was also dropped for a short period of time, the 429 was fizzled out by 1972/3. the 429 was used as the new luxo-barge engine starting in 1968.

I just had to point that out and laugh! I like it.

As for your description on the motors, you are right. The whole big block/small block thing really has nothing to do wirth Ford. Just Gm.

I also love the FE and y-block engines. Can't beat a good old 390. Planning un ploping one in a Ranger after I'm done with my 4.6 project!

i would love to drop a FE into a ranger. i spoke with a fella on myspace who had a gen 1 with a 390 on 38s. said it would roast the tires like no tomorrow.

if i had it my way, id get a Genisis 427 block and stroke it to a 484 and go to town, heh.

they can be built and anything can be done if you have the money...

FYI: 302 underdrive pulleys fit and line up on a 400 v8....

heard timing is a big pain in the *** with the m.

Bore size for the pistons is what determines ' big ' or ' small ' type of ' block ' from the GM factory. Not ' Physical size ' ( Even thought the names appropriatly matched ). Stroker motors of recent years have changed such as there are 400+ CID ' small blocks ', some sporting bores as big as 4.2125 inches ( Motown Blocks, good for 455inches in what looks like a plain old GM350 small block ) .

Don't forget the MEL (mercury/edsal/lincoln) and the FT (truck/industrial) engines. The FT engines are similar to the FE series with a few differances. The 391 FT motors have enough meat in the cylinders to be bored to 427 specs.

The MEL engines are only sought after by guys restoring the big Mercs, Edsals, and Lincolns of the late 50s to mid 60s.
