I have Chrysler's old formulas and graphs and I made my own with the info that I had back in the early 90s when I had my first machine shop. I'll scan them if I can find them but I seem to remember at 3,300 lbs a 12.20 et is about 10 hp per tenth, a 9.80 at the same weight is almost 17 hp per tenth. I broke it down from 9.50 to 16.0 and different weights can be used, a heavier car at the same et will require more hp per tenth.
