:thumbup Not a problem man... :beerChuck said:Sorry if that wasn't clear -- I wasn't trying to imply that the Cleveland and M blocks were the same (or similar), though I was in error in listing the Cleveland with the big-block bellhousing pattern. There are in fact some significant differences between the C and M even aside from bellhousing pattern -- they have very different main journal sizes, for one.
What I originally meant by that arrangement was that the 351M and 400M are the same block. They're very oddly put together -- they actually share everything except crank and pistons. The really weird part is the fact that they share the same rods, and the engineers made up the difference by using pistons with a VERY tall compression height in the 351M. Don't ask me why. Definitely not the way I would've designed it.
Actually, the fun combination is:jopes said:didja know you can use 351C pistons on a 400 crank with a little machine work?
Yea that's what I run in my 1985 bronco.THE 351W i found is bolted on to a c6 trans on a 68 ford f-100 that came with a 460 and thy swaped it with the windsor. wont that 351w bolt to my 351m trans c6. I am confused. or did they make a 351 w that bolted on to a big block bell housing
