Alright i got my stock 10b Front and rear w/stock 3.08 gearing. I now run 33s and am not to impressed with my acceleration. What would the proper gears be for my truck. I was thinking 4.11s but I really dont know what im talking about. I've tried Petersens 4 wheel mag's calculator and it says i need 3.11's. If it is that close, do I realy Need to spend the money? Heres my specs: 350 SBC th400 np208 10b F. and R.
