I am ready to leave the SM 465 behind. I am doing more and more comps and the autos have beat me to many times. So what do I need to do to make this thing survive. I am running a fairly strong 454, ORD doubler, D60 with 35 spline chrome Morly shafts and ARB, FF14b with Detroit and 44" boggers. So stock converter out? Kevlar bands? manual vaulve body? Any hard parts? What else?
