Hey FirstGen, my buddies '01 SS did 317rwhp stock. After longtubes and trueduals..350rwhp.(with tune) After cam 410rwhp through an 8.8...and then 541rwhp with the spray..Car still has stock pulley setup. I was thinkn' about 420rwhp on the motor with an ASP underdrive pulley. I just picked up and '02 Z28..bone stock. I will dyno soon and let yall know first hand. I've got long tubes for it and an ASP underdrive pulley. I'll let yall know the before and after. Just for fun!

Maybe he had "stock" LS6 heads on it? Your vette, all BS aside will not make more than 320 rwhp, ever completely stock. Probably less if it's an auto. I challenge you to go dyno it and see for yourself.
Good luck,
