Re: 400ci Engine Possibilities
I don't know if any 400 M's came to Aus.
Basically they are a Cleveland engine but the block is cast for the Big Block bell housing pattern that is the same as 429/460. The real difference to the Cleveland is the deck height. The block is cast for the longer stroke of the 400 and stroked down to the 351 capacity.
Most performance parts from the Cleveland, of which there are many, can be used on this engine apart from the intake manifolds which is a shame because that is a popular area for upgrading performance.
