From what I read it seems like the 351C mounts up just like a 351W. The 351M/400M seems to have the "big block" engine and tranny mounts.

Can anyone confirm or deny this???

Peraps a trip to the junkyard is in order...

Maybe I can look at some of these things for myself.


Thanks guys!

hi,
im not much into fords, but im pretty sure the Cleveland and the modified use different mounting and a different bell housing pattern. i think the heads may interchange but im not sure


thanks jeff

I'm pretty sure the whole 335 series (Cleveland, M, and 400) use the same motor mount, but this mount is different than the windsor and big block mount. The M engines (351-M/400) use the big block bell housing, while the 351-C uses the small block bell housing. I don't think the 351-W bell housing is interchangeable with anything other than a 351-W, but I think Woodz will have some good info to add, too.

The heads and pistons are also somewhat different between the C and M, because the M series has a taller deck. If I'm not mistaken, the heads are interchangeable between 2bbl Clevelands and the 351-M/400, but not CLeveland 4bbl's (M's didn't come with 4bbl stock). The intake manifolds and/or pistons are not between the 351-C and 351-M/400. But everything is interchangeable between the 351-M and 400.

The cleveland and winsor ( including small block) share the same bellhousing and engine mounts. The M block shares bellhousing pattern and motor mounts with the Lima or big block.
You have been confirmed on that issue.
