I'm going to stand by my position that 6 psi is still 6 psi. It will return the same percentage increase, regardless of engine size. The fact that 6 psi will yield an extra ~250 hp on the big block vs ~30 hp on the other one merely proves the statement that there is no replacement for displacement.
But the rules of the game are that we are using the ZZ572/720 crate engine as a basis for this fantasy build ... and a GM car. So this little side discussion is merely academic.
