A 3.55 is a good combination with the 700R4. I turn
2400 R's at 80 MPH and have a real good launch.

I'm running 3.31's with a
700. At highway cruise speed I feel that the motor
is on the ragged edge, and I don't have a high performance cam. I
believe that cruise RPM is right at 1700+ . I'd suggest you go even 1
gear set lower than 3.36. Either the 3.42 or 3.55 if its
available. It might make a slight difference in cruise MPG
but around town I'd bet the 3.42 or 3.55 would do better than what you are
gettin with the 2.56.

a 2.56 gear in the rear and a 700R4 is too low. Even for a

driver, I'd run 3.42 gears with a 700R4.
That's gotta feel like
it is lugging at 1,400 RPMs.
