Sorenson 1.408 under at Boise

I have been told that their car had an iron-head 427. A 1969 Camaro with iron block and GM factory heads is rated at 425 horsepower as of today. The classification guide shows that the class HP/weight factor is currently at 8.06 with an automatic transmission. As a natural "A" car it can legally run "B." The shipping weight is 3425#. By my calculations, in B/SA, it would weigh (425 x 8.5) 3612# plus the driver weight for a sticker weight of 3780#.

Three additional horsepower on the combination would bring the HP/weight factor below 8.0 and out of the reach of B/SA.
