Rear suspension recommendations?

Hi all-have tried 3 different setups on my '75 Duster rear and am unhappy with all of them. What would you suggest for a setup that gives me good launch control (I have an 8 1/4 rear with 3.55 SG and adjustable pinion snubber), great cornering(I have KYB Gas-a-just shocks, swaybar, and JCWhitney springs), and add 1 inch lift for the 255/60/15 BFG TA's I have on now?

You are asking for mutually exclusive goals.

Raising the car is diametrically opposed to good handling in corners.

The best setup for a dragstrip launch will also not be the best setup for cornering.

Also consider, the front end setup affects both goals, also in opposite ways.

You need to figure out your priorities first. It is possible to get very good handling with an adequate launch (assuming you have some power). But you aren't going to get an all-out drag racing launch from a car set up for cornering. Raising the rear is probably a bad idea in either case.
