Im not worried about getting an extra 50 hp for the same price if i can stay NA. What im looking for is a beast with power all the way through the PB. I have been looking at several cams and several heads but most ads are for the 5.0's out there. Dont seem to find many reviews/numbers on cams and heads for an 03 GT. I take her down the the track like once a month and drive it everyday. Anyone have a good combo to keep it very streetable and still be smokin the "evil" ls1's out there. Oh yah, Im looking for the most aggressive sound i can get while staying as safe as possible.. Thanks again guys, WhiteDevil
