Ok so I have the B+M weights, #4 and #5, I believe with stock springs. My 1-2 is about 4750 rpm and 2-3 is 5200+, I let off. I would like both around 5000 rpm, slightly over I can live with. Does one weight affect one shift or the other or both? What about springs? I am finding conflicting advice on what they do, some say they just spread the shift, others say raise or lower. I haven't played around much with the TH350 governor. I plan on a Transgo kit set at the firmest shift and Hughes 2500 stall. I have the modulator set to the highest shift points.
