Need advice, I have a 383, powerglide 1.76 gear and the car needs more gear in it. On motor I have trapped at 118 at 11.3, i changed the converter to a ptc nitrous converter. Best on motor now is 11.5 at 118. on nitrous I am expecting to be going high nines/ low tens I have only made a 1/8th pass on a 100 hit and have been 6.80 @ 102 in the eighth with no timing in it. Im going to be upping the pills and would like to put a gear in it to help out. The car starts to die off at 5,800 and up. already checked/changed everything. I used the calc and it says im imbetween a 3.73 and a 4.10. Just need some advice, thanks guys.(rear is a ford 8.8, yes I have a chevy setup in a mustang, and yes it was the best damn thing I have done!)
