Some of us are still using SS springs, but the Cal tracs are the way to go on an all out race car. For a few hundred bucks you can try 3200# or 3400# SS spring, Mancini Racing has a good selection. Make sure you get the aluminum front eye bushings and lube them up well so they pivot easily on the hanger bolt. Get some 2 and 4 degree pinion shims and try them to see what works best. These go between the spring perches on the rear end and the springs. Most guys are using the Rancho 9 way adjustable shocks, get the ones for a Dodge truck, or you can use a stock shock with a shock extension on it. Make sure the shock has enough travel and does not limit the amount the rear can drop. Simple way to check this is to put the car on jack stands under the frame and disconnect the shocks and let the rear end drop as low as it can go, then see if the shocks extend past the lower shock mount. Throw the pinion snubber away, if the springs work it will never touch the floor.

Now that the rear is right it's time for the front, I won't get into it, but 6cyl torsion bars or the Mopar drag bars are a good choice. V8 bars have to much spring and will unload the back tires and cause spin after the launch.

Good luck, let us know how it works out.
