and how do you know this wasn't just a little v6 pr 305 HO model firebird? What told you, "hey, this is a 5.7L Trans Am"? I'm really wondering how you knew that.

" Its a GT mustang a early 90's model it sounds very nice, "

put an off-road h-pipe and some 2 chamber flows on a 5.0 stang and it sounds mean.. Doesn't mean it's fast though. Early '90's eh...? how do you know it wasn't a late '80's with speed density and not MAF? Just wondering where all the damn ricers come up with the years to the cars that they race.
