I understand that i have a 5.14 Eaton rear and that 4000 rpm is the same with a 350 or 283. My question is what gearing in the rear will make me go faster easier. This thing was made to pull trailers and haul water to fires. My motor and tranny combo is time tested, but i don't know about a 5.14 gearing. I can make the 350 go faster but it aint worth nothing if the rear is to low. i haven't seen any ring and pinion sets for 1 tons either. Maybe i'm just not lookin in the right place
