No statement for the top class XX.00 or less.

Might be able to make engine 427/425.

If we have to go by the AMA Sheets, what choice do we have; its their, NHRA, Ball, Bat, and Glove
Speaking of the 1969, 427/425 combo.....it is now a natural AA car, therefore it can no longer run B. Class factor changed from 8.02 to 7.86.

The more interesting one to me...someone do the math on the 1969, 396/375 alum head combo. Previously the class factor was 8.16, a natural A car, and the new factor says 8.00......HOWEVER.....

New shipping weight 3238 divided by 405 hp is 7.99506....

So what is the natural class for a 396/375 alum head, is it AA or A? Do you round it up or not?

As the Stocker world turns....
