I think I would have gone the other way with the gears. But mine is a daily driver and I would like to keep the gas mileage. Put something around 2.80's in there, it would be like a five speed with one more gear then. I'm sure some one has a gear calculator around here. I'd like to see 1st doing what your 2nd is doing and so on. Cruising at 70 mph at around 1,750 RPM's.
