+1. The 400M which uses Cleveland heads is over an inch taller than the 351c and came with a big block bellhousing (except for a very few which came with the small block bellhousing, Pantera guys eat those things up though).

ford motor history
ford has what they call series(family) for there engines
351c is in the 335 series..
429/460 is in the 385 series..
then theres the FE series 360/390/428..
than theres the windsor family 302/351w..
it was chevy who started the small block/big block difference...
and I asked this how can a 396 be a big bb and a 400 a small block??
is it cubes or external size/weight or inline/canted valves that cast them into bb or sb......
