I have a 1971 charger that is topping out at about 90mph (monitored with gps app that is fairly accurate +/- 5mph) mild 440/727 with a cheetah full manual valve body forward pattern. Has a hughes 2k stall converter. Rear end is a dana 44 with 3.54 gear (46 splines on ring gear and 13 on pinion). Rear tires are 275/50/15, measure about 25in when car is on the ground. I know my rear tires are too small but i cant even get on the freeway at 60mph because this thing is cruising at 4k rpms. Any ideas?
