Have you selected a rear end ratio? I have a TKO with a .82 5th gear behind a big block Shelby motor with a lot of cam. My rear end ratio is a 3.31. If I had to do it all over again I would get a shorter (numerically higher) rear end ratio. The motor is happier above 2200 rpms, but most of the back roads (when there is traffic on them) where I live keep the motor just under 2200 rpms in 3rd and just a little too high in 2nd for comfort.
