The rear is 8-3/4" with a 741 case 3.91:1 gear sure grip that I think may have come out of a truck?
The tires are the 10.5"x27". That was my best ET, aftwards most were right at 12.00?
One of the cars I raced (a claped out race car with lexan windows, etc), ran the same MPH, but with much better ET and 60' times.

Anyhow, when i chassis dynoed this car, it was making 100+ more HP than the old engine which would run 12.50 @ 110 MPH, I figured the extra power and torque would get me closer to 11.50 and 120 MPH?



Not at that weight & Alt., be happy with the .7 & 7 MPH you got.
