LS7 vs. 350 ci LT5 mods - ZR-1 Net Registry Forums

No doubt in my mind that $4$, the LS7 is hard to beat for mods. You start out at 505hp, headers and a tune and you're looking 550 at the crank. I have a friend with a Silver 07 Z in that configuration. Not to mention it looks like a Great White coming up on your 6 when viewed in the rearview mirror. For a 5.7L, the LT-5 responds incredibly well to even small mods like porting and better exhaust. So the potential is there but the
OHV v OHC differential will always be low end torque which the LS-7 has in spades. Of course, we'll need to see what Todd has cooked up with his 427.
