I picked up a Super T-10 or my son's Nova and was wondering what ratios are in it. The casting numbers are 3-10-81 MLT-11D1 13 04 065 903
FpC4

Does anyone know what ratio gears this thing has? I think it is out of an 81 Z-28. Bob

How many rings are there on the input shaft?
2 = 2.43:1 first
3 = 3.64:1 "
6 = 3.42:1 "
