Shawno, you are going to hate the 3:08 with the 700R4, I have had this combo with a 26" tire for a few years and just bought a 3:73 carrier and gear set.I turn around 1500 rpm at 65 and it bogs down the motor just getting on the gas.If you had a 3 speed auto you would probably be fine but on my truck cruising speed is definately out of the motor powerband and my vacuum gauge confirms it. Also it is hard to put 350HP to use with this combo.
