Ive got an 83 jimmy w/ 350 4bolt (of course) and a 700r4 behind it. My question is, which torque converter to use? would a stock converter be best, or use an after market with a stall? I would prefer to keep rpms low, right? my plans are to run 5.13 gears and 38 or 39.5 tires. My motor has got a low end cam, roller rockers, and soon to be tbi. whats the best t/c for this equasion?
