    I tried a bunch of arrangements when I raced my TR3. I agree that
    you want something close to a standard 3.7 final drive. My favorite
    setup was close ratio 4 speed, A-type overdrive and 4.55 rear. The
    0.82 overdrive gives 3.73 in 4th overdrive. Your overdrive ratio is
    similar. - Larry Young<br>
