Mejum size block
It's kind of a big small block. As mentioned, Ford considers it part of the "335" series engines. However, if you take a 351M head and place it on a 351W block, it will fit and the head bolts can be installed. So that means that important design features like bore spacing, head bolt pattern etc. were copied from the "small block" series.

I say all 335 series motors are small blocks, the 351C uses same mounts and tranny as a 302 and the other two are just alterations of that original small block. Heck like beanscoot said you can bolt the head on a 351W or a 302 that makes it all small to me. Surely a Big block should have a bigger bore than a 289 right? Well except some FEs I think.

right....the 351M/400 bolts into the same frame perches as a 302/351W. Can't do that with a 429/460, or FE. Some of the first 400's had small block bolt patterns as well. The 351M came about 4 years after the 400 as a destroked 400. Crank and pistons are all that's different. Even the connecting rods are the same.

Which part are you talking about? The rings also fit 289s,302s, all 351s and 400s.
The rocker arms and distubtor fit 351C, 400, 370, 429, and 460s
Valve covers, timing chain cover, timing gear parts, fuel pump, oil pans, and oil pump fits the 351C.
clear as mud, huh?

Yes I know, but still not a direct bolt in.
Let me re-phrase that...bolt in without any creative mods or aftermarket parts.
Quesey: may I pick yer brain on your 351W into '86 Mustang?
