Sean,
With the 3.73s and the .68 overdrive of the TKO500... you will be turning 2200 RPM at 65 MPH. This is calculated with the 17" Eagle rear tire that is about 25.25" in diameter.

If you drop down to a 3.46 with this setup you are only dropping to 2050 RPM. Better to have the extra off the line...
