So many ways to get there. First you need to determine what you want the car to do, handle well, go fast in a straight line, etc. IN MY OPINION every a-body that is street driven NEEDS disc brakes, bigger torsion bars, and a front sway bar. Once you've driven one that's set up right you won't like them any other way. And, yes you can make a big block a-body handle well.....
