I could give you an idea to start with if it were a drag car only. For street would be heavier and for track would depend on the type of track.
If anyone can figure this for you it will be Mr Billy Shope. He is a mamber on here. You can send him a PM or you can possibly find him giving input here in the suspension section of the forum. I have not seen him for several days though.
Bubstr gave you some pretty good advice.
