Whipple states they have a kit that will make 600hp @ 7 psi for the 5.0 on pump gas. I really want to see what Kenne Bell is going to offer.
And getting more wild than that will require changing some internals and at that point you can bring the CR down.
The LS3 still has a 10:7:1 ratio itself.

Think there is argument on both sides for compression ratio. I will say the LS3 is good for 13 psi max on stock internals. More will start to bend rods.
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.
