Power advantage between Ford 351, Mopar 340 and Chevy 350??

The Chrysler would still be number 1 because of lifter diameter and bore spacing.

I see what your saying, I think the OP was getting at something like if all 3 had an edelbrock rpm top end, comp 285 cam 10:1 cr 1 3/4 headers would the power numbers be similar.
