Rc/sb 5.3 six speed?
#3
Plan to go testing next week.

That 3.08 geared 6 speed will yield the same ratio in 1st gear as a 4l60e with 4.10 gears. So you get all the benefits of 4.10s, but you still will get great highway gas mileage with the 3.08s. My only concern with 3.08s is that the 5.3 doesn't have enough torque to lug up highway hills at 1500 rpms.
