I have heard that the 351-400M motors were alot wider and taller than the 351C. When I was dooing research before putting my 351W in my 73 I was told the 400M would not even fit in my engine compartment without major modifications. The 351-400M motors also use the same bell housing as the 429-460 big blocks.
