I have a question about the gear ratio. There are 2 different set ups for the over drive. 1 has .8 and the other is a .64. The first is listed as a rd race while the second is listed as street. While there are several threads on this tranny, I am wanting 2 know which 1 u chose and how did u like/dislike the over drive. Some of the threads have the owner wishing the had chose the rd race while others feel they make the right pick. If u know the rear gear and your tire size please list it. I'm wanting 1 and I just want to make the best pick 4 me. Thanks n advance.
