I'm sure my car was all wrong, but I used what I had available at the time- 25.5" slicks, 6.17 rear end gear, and 3.64 first gear.

As far as your horsepower, weight, and potential ET, your numbers sound about right. My car was about 250 horsepower, about 2,300 pounds, and launching at 9,000 rpm resulted in high 11s at about 110 mph. With a modern clutch, a lighter flywheel, and a closer-ratio transmission with a taller first gear, I'm sure it would have gone faster.
