Dennis,

My neighbor across the street has a early 50 truck, stock 235 and about a 3.00 rear end. He complains that he has to slip the clutch to get up the driveway. I'm running a car with stock 235, original wheels and tires, 3.73 rear and T5. With the .72 overdrive it really rolls down the road for cruising at 60 to 70, at 50 to 55 you really have to down shift to pull much of a grade.
