But went back and added 200 lbs to total weights and recalculated HP
ET--650 HP
MPH--525 HP

I have rule books from the 60's will look it up, just to know.


I think your calculations are pretty close. The hybrid headed E/D and J/AA Fords are getting over 650 on the dyno, and subtracting about 10% for drivetrain losses puts you back around 600 to the ground. I think e.t. is a better predictor of power-to-the-ground than mph as converter slip or clutch slip can adversely affect mph by a few mph.

By the way the Ford hybrid head was made legal when FoMoCo cooperated with some of their racers and assigned a Ford part number to the head and put it in their Performance Parts Catalog for sale.
