I went from 3.73s on 32s to 4.56s on 35s and its only a 300 RPM gain on the road. Wanted and should have gone 88s. Deal is I only run a 4 speed and its near a K RPMs. Then came the 4x1 in the 300 . OH YEA ! Thats the ticket right there. Its just how bad do you want to go slow and have soooooo much control ! FjR68
