Lookin for NHRA Stock Class ET/MPH from 1970-71

[Dwight Southerland]

I believe the CobraJet factoring was in super stock classes. Red Anderson once told me that the first stock factor was on the 255hp 350. The super stock classes from 1967 through early 1970s were the hotbed of factoring. When Stock was reintroduced in 1972, the SS factors were carried over to them. I know that the 396-375 Camaros carried a factor of 415 until 1981 from the efforts of Wally Booth, Bill Jenkins and others who raced them in SS.
