Alright I have a semi-built 4cylinder. Was an automatic not has a 5speed t5. If im not mistaking my rear end should have 373 gears in it right??? Well the rear end under my car is not the original one so I have no idea whats in it...It is 7.5 but I seriously doubt theres 373 gears in it. Has bronco II 5lug axles. But now for the reason of this thread, the motor has a good bit of power but this thing from 1st gear through 3rd is like driving a damn transfer-truck. The acceleration is terrible, 4th gear is pretty good and 5th is good till certain high speeds then theres a noise like the rear ends gonna blow out. So my question is whats a good gear for good acceleration with a 7.5 rear end with a t5 5speed tranny? I do have 17inch cobra r rims but I doubt there that heavy to kill my take off that bad...Any suggestions?
