ok heres the deal. i got a new stang. im running 13.80's in the 1/4. i want cams. i plan on doing heads down the road. but for now i want cams. i don't want to change anything else. not injectors or computer. with the hottest cam i can get without having to modify everthing else, what can i expect to pick up in the quarter mile. any recomendations are apreciated thanks
