So true, when I hear guys talking about gears and overdrive to gain fuel mileage, all I can think of is how litle torque the old motors make, and how are they ever going to get mileage working them that hard.
My truck didn't change much in fuel mileage going from 3.42 to 3.08, at highway speeds (65-70), its the wind that kills it, not the rpm.
