LS1 goes 10.73 @ 128.7mph - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I know it's not the racing section, but, I wanted to show the potential of these little motors. The truck has a 4L80E in it with 4.56 gears and a 30" drag radial. On the freeway at 65mph, it's at 2,300ish rpm. Still get's about 13.5mpg. Even running a single plain intake with dominator TB, throttle response and drivability is awesome, even with the 243/250 cam that is in it. It's all about the tune!!
