The first two ID #'s are C2 It appears to be a 351 C but it has a small block bell housing. The heads seem to be cleveland's though. Possibly boss motor?
so a 351 cleveland would is a small block with 351m-400 heads? I have no way of putting a picture up but I will try to get the #'s. Dont really deal with cleveland motors but am interested in this one. It also has weird motor mount bolt patterns.
as far as I know, the bellhousing's are different than a 302...the cleveland is supposed to be the same block as a 400? I think, and there aint no way to bolt a 302 bellhousing to my 400 that I can see.....if it's a boss 302, it is a 302 block with cleveland heads....
well all 351C is small block. a 351M/400 is a big block. The heads on a 351m/400 has 2.04 intake valves and 1.66 exhaust. where on a standard 351C 2v has same valves. However the 351C 4V has a whopping 2.19/1.71 valves. So if the cleveland motor is a 4V GET IT.

A 351C is a small block and will not bnolt up to a 351M bellhousing. However a 302 bellhousing will bolt right up to a 351C. same bolt pattern same size. 289, 302, 351W, 351C all have same bellhouse.
351M/400, 400, 429, 460 all have same size bellhousing but a 351M fly wheel is balanced diffrent than a 429 or 460 so the flywheel will not work off a 351M on a 429.

oh ok....I thought the 351c and 351m and 400 was the same block.....I'm new to the 400 and trying to learn as I go....
Im still learning on the 335 series engines also. I do know however the 351C is small block because i have one. The also got 4 bolt main holes in the block so you can use 4 bolt main caps on the crank.
In the interest of promoting harmony and civil discourse in this forum it has been decided that there are a couple of guidelines that all posters to this forum should follow:
2. Avoid speculation on whether the 351M/400 is a "big block" or "small block". These are generic terms which generally apply to Ch*vy motors not our beloved blue oval mills so they really have no place in this group. The 351M/400 has elements relating to both the 385 series and the Windsor series and attempting to categorize them is futile, especially when using monikers which FoMoCo never adopted.
