If you want similar rear gears you have.
You are posting about 4.77 so you will have to go to 4.88 for a 8.8,(Motive Gear). This is the closest that they list. They will probably be better. Quicker off the corners. will add some RPM, hopefully to about 6000.
I race on a 1/2 mile asphalt & was using 4.10 X 1.46 = 5.98 getting about 6200 RPM.( C4 in second)
Changing to 3.90 X 1.55 = 6.04 (4r70w in second)
My new roll cage is on the way + new racing nose. Will post pictures in my listing in "Racing" soon.
