Well, I think at minimum I'm gonna need to replace the 5th gear set also, since I went out earlier to count the drive gear and the main shaft gear...not good...drive gear is 25, main shaft is 51, which provides a 0.490. Looking at the numbers, someone was showing me that with the 3.38 gears I really need a .86 set, that would put me right around 2150 rpm at 65mph.
