Ok guys, I've had my 05 z51 6sp car for awhile now and I'm looking at doing H/C/I with a 150-200 shot in the future. Don't have the funds for spendy TFS heads or etc but I'd like to make as close to 500whp na as possible. looking at maybe ls3 heads. My questions are, is the cnc head worth it over stock? what cam would be best with ls3 heads and a fast intake? what numbers have you made with a similar set up?
Car is daily driven and at the moment all stock except an u/d pulley and a vararam. the car recently dyno'd 371whp/360wtq.
Pretty new to the ls world so feel free to correct me or point me in a better direction.
I believe when you go with the LS3 heads you also need an LS3 intake manifold? I also remember reading something about being able to trade your LS2 heads towards LS3 heads somewhere...
