I'm running 33" w/3.73 gears and a 700R4 behind a warmed up 350. Not alot of miles but I've driven this combo many times before and I'm fine with it.
edit to add, e-locker up front and a G80 in the 14 bolt out back.
My daily has 33" w/3.55:1 gears with a manual NV5600
A little more torque from the engine though.
