I agonized over the gearing decision when planning my build. 3.31 or 3.54? .82 or .64? I spread sheeted it to death and wound up choosing 3.54 and .64 as I drive it in town about 90% of the time. I never use 5th until on the highway, where it cruises at 70 mph/2000 rpm. There is about a 500 rpm drop between all gears except 4th to 5th, where the drop is about 1000 rpm. Since a Texas highway speed limits are 75 and everyone drives 80, this combination is perfect for me. If I had planned to race the car, I would have gone for the .82 OD.
