I'm finishing up my 5.3, 4L60E, NP241 swap this week. While I was doing the power train swap I also installed a 2" BDS lift kit and a 8.8 rear axle. When I bought the 8.8 the guy told me it has 3.27 gears in it, haven't opened it up yet to confirm. So any of you guys that have done this engine mod, what gears/tire size are you running. I have already done the calculations and know my RPM at 75 MPH with 4.10 gears would be 2192. I'm pretty sure I'm going to go with installing 4.10's to match the front but just wanted some opinions. I'm running 33" tires.
