FWIW - Using my tire/rear end info (I'm pretty sure I've got a 3.49 rear end)... I don't think yours are listed. Just for clarification are these the approximate speed ranges in 4th gear?

mph = (rpm x tire diameter) / (gear ratio x 336)

31.4 mph = 1400 * 26.3 / 3.49 * 336

42.6 mph = 1900 * 26.3 / 3.49 * 336
