yeah, not alot of aftermarket following on that, although there has been an outcry in hotrod magazine for V6 camaro mods, as well as GMhightech magazine, so keep an eye on those to see if they answer the call. maybe even give them a nudge yourself. but best bet is pull the motor, and go hot rod style, port and polish the heads, custom ground cam from comp cams, they might even have on the shelf grinds, not sure actually, thermal coatings, anti friction coatings, crank scrapers, roller rockers, street flow valves, three angle valve jobs, and the aftermarket cold air intakes, exhaust, and programming, probly your best bets.
