RPM's

3.23 isn't that much of a difference from what you have now, still vote spare 2.94, and big tires as the best option here. :angel5:

If you have a tight converter you should have no issue with slip cruising a few hundred RPM below stall. Try it out, use a tach and see what your RPM vs speed is at compared to what your cruise would be with new gears, and compare with this tool. Rev it a little while your there to see how tight everything is.

Play with this to get an idea, and measure your tire from center of hub, to ground to get accurate size.
