What the heck, another "what'll it run" thread

Skypower, I geared the car so I wouldn't run out of motor before the end of the track in 3rd gear. I could put some more gear in it, but I think I'd have traction problems with the amount of gear I'd need to keep it in the power range in 4th gear. The spread in the 4L80 is 2.48, 1.48, 1 and .75, so it really doesn't make up for it. It's essentially the same gearing as a 727. Plus, those 4.250 stroke cranks build piston speed real fast and turning it too far beyond 6000-6500 is asking for trouble. Honestly, I think 6500 is pushing it.
