    If its a 7.5" I would go with a 3.73.

    Realizing that for every .1 in final gear ratio change, the engine rpm will increase/decrease about 125-150 rpm. Dave

    Thanks for the input. I currently run 4.10 and crank about 7500. It's a hammer once it gets going, but sometimes it's a little too late. Looking for a gear combo that will help me get off to a little quicker start.

    i guess the question is what rpm do you feel safe with? you might have better luck going with a 2.14 and 3.73 gears to accelerate faster,thats a 7.98 final versus your current 8.07 final
    No matter how hard you try...you cant fix stupid!!!

    If you build it right...it will turn left!!!
