I am wrestling with the same decision, but I have been told by quite a few folks that since I have an AODtrans [in my '03 GT] I should go with 4:10s over 3:73s. Currently, I just have the stock 3:[too weak to remember] gears. I don't want to have the '73s installed and kick myself for not going steeper. I may participate in a few flashlight races but beyond that it will be my street machine and I want a good grunt off the line. I understand I will lose top end speed, but I don't think that will occur within a 1/4 mile run - is this correct? Perhaps one of the major deciding factors is whether your car has an autoOD or man. trans?
This is a good topic and I'm sure others continue to scratch their heads over which gear ratio to choose.
