technology is a wonderful thing

Just go the trans computer programmed for the Gearstar 4l65E that's behind the LS1 in my '73 C10. With 3.08 gears in the stock 12 bolt and 27 1/2 inch tall tires, it cruises effortlessly at 1,700 rpm at 70 mph. It does 80 mph at 2,000 rpm without the engine lugging.

speedo isn't working yet so i dont know what the mpg is, but man is it a smooth ride.
