A simpler and far less expensive alternative is to go with a bigger torsion bar. Most of your body roll is because your A body is nose heavy from the big block.
Heres what I would do;you dont have to do all of it.
Relocate the battery to the trunk.It'd 60 lb's or so off the front end and will help the weight transfer when launching the car.
Buy and install a fibreglass front bumper. This is probably another 30-40 lb's. Remember,the less weight the spring is supporting the better. It will act like a stiffer spring.
Buy and install a 1" torsion bar from just suspension at ebay.Thier only $199/pair right now.
Install KYB gasadjust shocks all the way around. These alone will stiffen up the handling lots.
Re-arc or add a leaf to the rear springs.
Front and rear sway bars.Aaddco or other.
Make sure the rest of your front end isnt worn out. Rebuild it,get an alignment
what is the gearvendor and where can I get information and pricing?
