I am not convinced the 5.0 will make up for it's limited N/A capability on the FI side. (In comparison to the 6.2) There are folks with the LS3 FI laying down 600WHP on pump gas. That = around 690HP at the crank. I feel that will only be achievable with race gas or meth on the 5.0. Time will tell.

I agree the 6.2 mod for mod should make more power than the 5.0 because like it is said their is no replacement for displacement.
But I think we will need to wait and see when the GTs hit the street. The heads are supposed to be flat out amazing. Better than the GT500 heads. Depending on their efficiency they might can help the 5.0 handle a little bit more psi from a supercharger. Remember the compression ratio is not necessarily the enemy, it is detonation.
And another thing to remember is that while that Camaro hits that 600rwhp mark the stang would be able to dyno 575-580rwhp to keep the power to weight very close.
