The gear calculator says that my effective ration right now is 3.53. says new gears 3.94, low gears 4.3, and high gears 3.59. Im looking at getting closest to the low gears right?

Lower gears will give you more take off and umph...but will increase the RPMs on your top end. Seems like 4.10s would put you closest to the stock power band, but that sucker will prolly jump off the line with 4.56s.

Then I think 4.56 is the way to go. I'm not concerned with mpg much....it's a Hummer after all the price of gas pays my salary so not an issue for me. I want it to be torquey! I'd like the deuce to be quicker than my dads 6.7 Diesel F250
