Hey guys just wondering if anyone has had experiance with big cams in an ls1 street car and what power is possible to acheive. I have an ls1 with 4200 rpm stall and manualised auto and will be getting 3.9 diff gears. With basic bolt ons like 1 7/8 extractors hi flow cats and twin 2.5" exhaust, underdrive kit and otr intake etc. Would 300 rwkw be an unreasonable figure to acheive with for example a GMM Turbo killer cam. cheers any help would be much appreciated.
