I would also consider the 93 to 96 Trans Am or Formula Firebirds. Years ago my neighbor had a 95 Formula convertible with the LT1 and a 6 speed, he had a Paxton installed on it, damn that thing was quick, and fun to drive! Probably still has it, but family and kids meant that it was parked some time ago. He wasn't a car guy, but he had very deep pockets and liked to go fast.
