How much cash do you want to spend? A 00 Camaro Z28 has something like 310-320 horse. A 00 Mustang GT has 260. Stock for stock the Camaro is faster, but a nice one will cost more than a GT. The LS1 Camaro engine has to be removed from the bottom, I hear its no easy task. The 4.6 isn't the easiest to work on either, but I think its easier than the LS1. This is going to start a bunch of different opinions flying to be prepared. IMO, buy a nice stang and mod the crap out it! :eyepoppin
