The gearing is almost perfect, compared to the Muncie 4 it replaced. With 14" rims, I kept smoking 1, 2, 3, and my speedo was off. Installed 17" wheels, and speedo is dead-on and no more unintended burnouts. The 3rd gear breaking loose was unnerving. I swapped ends a couple times. Of course, that was with my 3.4+ bored, valved, opened up and tuned. I can't remember my hwy rpm. I want to say 1700 @ 70? Ill get it out this weekend and reply with the speeds.
