My 3800# car with 3.50 rear gear & 28x10.5 tires has run 10.62 @ 127 with my home built 4l80e, but it still isn't shifting right from 2-3.
Hard parts from Coan , standard VB with Ross-Lock .
Big difference in the quality of the parts side by side.
Box not in the car yet cause the current rebuilt 4L60E is finally holding up just fine.
