I think 4.56 with 35's is what most folks report their happy factor at. I've been trying to decide between 3.73's and 4.10's for the 33's I'll be going with but from the more I read the LS motor and 4l60E is going to be just right with the 4.10's, but I do plan on highway driving as a daily driver so it might not be. The upside is now that I have a 14 bolt it is super easy to swap gear sets. All you have to do is keep track of what you pull out and replace seals. Once I get rear gears right (leave my front driveshaft off until I do so), I'll probably find a spare front 10 bolt and swap all the 3/4 ton outers to it and set up the gears to match. Right now I have the caliper brackets, which apparently is the unobtanium bits, so after that I think all I need is the hubs, rotors, and to do some wheel shopping. I think I am just going to go with some 17 x 10 inch steel wheels with the circular opening in them, with a powder coat black finish.
