I've got one of those lumpy 482's that Keith puts together, 3.50 rear gears, 15" tires, and the .64 TKO600. I must admit 5th gear can buck a bit around 60mph, but from 65 up it really hits the sweet spot. From 65 to 90, (that's as far as I've ventured), the rpms hardly rise at all from slightly north of 2K. I went from a 90 mile trip on the back roads using nearly a full load of fuel, to 90 miles on the highway with half the fuel.
I did not plan on tracking the car, so I chose the overdrive.
