In Depth report on the Camaro's LS3
i see no reason y it shouldnt surpass that quote.
even with a bone stock lq4 6.0 and t76 i put down over 570rwhp
and this was in 03'
the modern lsx engines feature improved rings, piston material, wrist pin and connecting rod design and most if not all oem lsx are equipped with mls head gaskets.
i think 550rwhp will be more common with ls3'
as 500rwhp was with ls1's with aggressive setups on the stock motor
It's going to be easy to slap a blower on this car since the motor won't be up under the cowl, so it will be easy to do.
