Local guy here pulled 405 with a cam only and LS6 intake on a 98 TA. That's all the info I have, he was telling me about it last fall (2009.)

If anyone here remembers, there was ONE guy here who claimed he made 400 on just bolt-ons and a good tune. But on a stock cam, it won't happen.

^ No such thing as BEST. (other than the FAST crowd). Anything on these cars makes power... Except a TB spacer and smooth bellows. Just do some research to find what will work best for your goals and wallet.

Short answer: No.

And what's your definition of "Best?"
