Whither 1966 D Darts for Stock

D Darts:

Well I just dusted off my 1966 rule book and discovered a couple of interesting things. First, the classes and weight breaks were not uniform. Stick cars started at S/S, then A/S down through O/S. But the automatic cars stopped at J/SA. The super stock class was 0.00 to 6.99, then as follows: A, 7..00 to 8.69, B, 8.70 to 9.49, C, 9.50 to 10.59, D, 10.60 to 11.29, E, 11.30 to 11.88. and on down the line. How they came up with these breaks is a mystery. Another interesting note is that if your car wasn't in the classification guide, they just weighed your car, subtracted any fuel at 6 lbs/gal and divided by the factory advertised HP, and that was your class. There were no NHRA 'FACTORS' for HP, just factory advertised ratings. So the D Darts fell in the D class at 10.60 to 11.29 lbs/hp. Thsi sure brings back memories of a simpler time!
