CONTROL FREAKS IFS A-Body 440 setup

Agreed!! Just a car guy looking for input! I have the motor already ( just needs build up ) so small block is out of the question. Hence my original question. Will probably do what was suggested before for all the other suspension parts plus discs all around. Since we are on suspension, what's the better size torsion bar setup? PST has 1.03 and I've seen 1.08-1.2 I think. What the most I can do? If anyone has thoughts!! Thanks again!
