C = Cleveland, Ohio engine plant and is the 351 small block. (Don't know if a 400C exists).
M = Modified 351 and 400 for trucks, yet considered a small block

The housing for the timing chain/gears on the 351C is cast into the block where as the 351W has a removeable housing much like the 302, IIRC. 351M and C valve covers are the same. 351W valve covers share with 302s. Someone much more educated can tell you the difference between the M and Cs as I don't have a clue.
