I have a 1990 GT 5.0 auto, i love the look of the 82s and that they are carbed the performance department is a little more open, are there any ups or down to the 82s? Any major differences between that and my 90? Thanks, im just looking for a powerfull street car and my 90 needs too much work, also looking for an 88 or 89 notch. THanks
