Hey everyone. I spoke with DOC last night about what you were talking about. I don't necessarily want the RB26 6 speed, just a six speed. I may just have to get a custom main shaft built. I want to run the same 1-4 ratios, a slightly closer 5th and ofcourse a sixth. (Goal to reach over 200 MPH) I know it's a bit crazy but I would like to see about doing that.
