700r4 is in.
I just got my truck back with the 700r4 in it. It seams that the gears in the rear end are way to hi (3.07). Going down the road I will be running 55 mph and the rpm will be 1500, at 60 mph it's turning about 1700. My question is what are most people using with the 700r4 in a auto. What is the best ratio to have to get the best gas mileage? The truck is a 71 gmc swb with a new 355 engine.
