I8I made this a seperate post. This looks like a really nice street car. Hitting the track once in awhile is always fun. Having tires that don't spin is a huge help. Beyond that, you start getting into how far can I go to make it quicker? Beware that 4.89 gear, stock 23 spline, stock 8 3/4, stock rear supension, stock style shocks, heavy car wormhole. Been there, done that. Try it first with some good tires. Do you really like to race? If so? Then you have a decision. Take a really nice car and make it not as street friendly. Or build/buy a dedicated racecar. It doesn't have to be an 8 second deal. But if it's a dedicated car weight can come off. Cam, gear, and clutch/converter can get into the correct deal. This is coming from a guy that has a nice 12 second street car, a more radical but drive anywhere 11.0 car (that at one time was my only real dependable street car), and a dedicated 9.0 drag car. They all have their place.
