But you still might find the mid to upper 60's to be troublesome. With your setup, fourth gear needs 2800 RPM to hit 65MPH, using a 26.8" rear tire, which is what my MT 295/50 tires are. A shift to fifth at 65MPH drops your revs to 2300RPM, which your engine might not like.... I think I did that math right. The truth is, you really won't know for sure until you have the engine nicely broken in and tuned to perfection.
