Get a 98+ Camaro if thats what you want. 98's can be found between 3500-6500 in decent shape, usually with mods already done. Can't go wrong w/ the LS1 which excels greatly with mods. Full bolt ons and a huge cam can get you close to 450 wheel HP, a milder cam, with some headwork can get you 450 and make it a little more streetable. Huge cam, huge heads, and a ported FAST 90/90, get you closer to the 480-500 range to the wheels.
