    Hey,
    I was wondering. I have 3.73 gears and I have an AOD. I was wondering if it would be a good investment to put in 4.10s? I would like the kind of low end torque a 5speed has, so would this help? :) The previous owner put in the 3.73 gears, so that's why I have them. I also am planning on doing:
    -AFR 165 heads
    -Holly intake
    -Ed Curtis cam maybe
    -3000rpm Stall conv.
    -manual valve body
    -upgrade fuel system,
    -then later on a Dart block stuff w/ 331 rotating assembly
    -then a turbo :)

    All will come as money comes (OverTime helps :nice: )

    I just did this swap and it helped but it didn't give me as much as I was hoping for. I think I might have gotten a tenth or tenth and a half more ET out of it. The low end is better. I might notice more of a difference if I ran slicks on my car because it does spin them more then before. If I had it to do over again I probably would just go with more converter.

    What's a good converter then you think w/ 3.73s? I'm going to get a converter from PI, by the way :)
