Yes there was a good difference from stock to I/H mods in my car. I wouldnt second guess 2 cars with a LS3 vs LS2 race. Yours is a Z51 so a non-Z51 might put up a hair better of a fight with the longer 1-3 gearing, but wouldnt make a HUGE difference at the end of the day.
well the stock c5z06's are faster than stock ls2's also.... i think a fair race would be a stock c5z06 and an ls3....???
but i'd be down for a run since i'm curious as to just how much faster those ls3s are..
