GMT 400 obsessed Swede.
I figured the RPM would be kinda high with the engine/trans and rear end along with the tire size - 265/70/16. When I had the 3500 in there, driving at 70, my RPM would be about 2300-2400.Screaming? Nah.. 3.73's out back are pretty tame compared to 4.63 or 5.13 in the 3500HD's. The 225/70/19.5 tire is about 32" so that helped negate a little of the steep rear gear but not much. You still get 0.73 5th gear...
