lol, nice kill!
I second that s/c. that would be badass! If you cant swing the supercharger just go with the cams, header, exhaust stuff like you said. some mods are better than no mods
Edit -- btw, those pics in your sig look nice.. thats a sharp car
get some interior pics in there as well. Thats one of the things that makes the GTO so nice. A muscle car with a pretty nice looking interior
