Traditional Super Stock never has had the 250lbs adjustment rule.

Use to be you could run your natural class and next heaviest. If your car's natural class fell in the middle your were not allowed to go to the bottom of the class.

Per your previous example Shipping wt of 3379 ÷ by hp factor of 300= Power to weight factor of 11.26. Natural Ss/J car. Minimum wt. for Ss/J would be 3379 + 170 for driver 3549lbs rounded down to nearest 5lbs. 3545lbs Ss/J minimum. Or you could move down to next heaviest class. SS/K 300hp x 12lbs class plus 170lbs for driver. SS/K min. Wt. 3770lbs.

This is why you saw more diverse cars in traditional SS then present day because some different models of cars "Fit" classes better than others.

It was a complicated system. So NHRA changed it to you could go to the bottom of your natural class or one class heavier.

Stayed that way for about 5 years. Then it was changed to traditional SS can run their natural class, next class heavier, and next class lighter. You can go to bottom of class.
