    27.58 is the tire diameter. I think the 4.10s will work great with that tire size. Do you have an idea of what rpm you want to run at a given MPH or gear range. Are you going to take it to the track? 1/8 or 1/4 mile?

    Mainly street use but I would like to take it to the track to see what it can do.

    it&#39;s probably a little high RPM for fuel mileage but it&#39;s where I like it.
