Hey gungho, I have nothing to say for or against Pro Comp heads because I don't know anything about them so I am not here to argue or jump on you so don't take it that way. But as far as someone having a car without a parachute and you questioning how fast it can be, my car has no parachute and if I ran at a sanctioned track they would throw me out. The few tracks I frequent are non sanctioned so I don't have to have one and they have plenty of shutdown. I have a Camaro like the one you have so of course I like it. If your ever in Texas(I didn't notice where you are from) shoot me an email and we can meet up and go have some fun.
