    you didn;t say which trans and car type 8)
    but--with an automatic 3;73 or 3;91 would be a good combo----with a clutch 3;23 or 3;50 would work good

    go to high and your engine combo will SUFFER TERRIBLY ops:

    Tall tires = tall gearing. The land speed racing guys bolt on the tallest tire they can turn.
