    Gear change?

    I'm considering changing my 3.73's to 4.11's should I see much of a 60ft difference? my set up is a mild sbc,4spd,12 bolt 373,26x10x15 m/t slicks.My previous 1/4 mile times have been very disapointing and every one says its my gear ratio? my 60 ft has been between 2.05 and 2.09

    the 3:73 gear ratio is a good street/strip the 4:11 works just as good
    on the street as well, what carb and intake are you using, and
    you said mild sbc, roller or hydralic cam? with the right combo the
    3:73 had worked great with my 383, if your sbc is stock you might
    try some mods to boost up hspwr, using the 4:11 with no changes
    to the block might give you a slower time, not sure, have never tested
    on a mild sbc, i could be wrong, good luck bud :wink:

    yea with that combo you would benefit with the gear change, the
    vic jr is a very good flowing intake, you might consider a 850 dp
    running that compression, you will always have to use high octane,
    your cam is over .500 lift, is it roller or hydralic? good luck bud :wink:

    SO you guys think its worth the time and $$$ to change to a 4:11 gear? Do you think I will see a noticable difference?
