Hey Ron, You really dont need anything more then a 3.23 or 3.42 gear with that first gear ratio. Doug

I agree with Doug^^, 3.37 X 3.23 = 10.88 to 1 launch ratio, close to 10.00 is what you want to help with traction for Drag use. The 3.42 X 3.37 = 11.52, a taller tire will lower it also.
3.23 X .67/5th = 2.16 ---- 1960rpm @70mph w/26" tire
3.42 X .67/5th = 2.29 ---- 2075rpm @70mph w/26" tire
