    New guy to Ls1.com

    Hello fellow Ls1.com members.My name is John.I use to 1/4 mile race,but now I'm gonna autocross my car.My last dyno ran a 387 rwhp.I'm rebuilding my motor a few months from now. I want 40 more rwhp. Would a port and polish-valve upgrade do the trick? Or should I go with a stroker kit?
