figured it would be an ls1. im not really into vettes so i dont knwo the body styles for the years. but i know the motors. only think that sucks is you can but a ls1 camero. which yes is slower but if you change the cam in it then the motors are identical and the camero runs faster. lol chevy screwed up one of those years and made the camero faster thne the vette. so they changed the cam in the camero to make it slower. lol i think thats how it went.
