Very much interested. I have the Rule Books from 1958-1968 (but not 1969-71) but the only Classification Guides I have are the current ones on line. There are good to get weights, but still a big spread eg 57 Chev from lightest to heaviest. So just knowing its a 57 Chev doesn't mean much. And of course 68 Chev could mean big car, Chevelle, Camaro.
For example, in the sheet Rich B already posted it lists Kost's W30 in F/SA. NHRA says 3720lb for the 442 W30 and 3720/370 puts it in G/SA in 1970. So I figure, well maybe it was a plain Cutlass at 3607lb which works for F/SA. If I didn't guess at some stuff I wouldn't get very far.
I think they were factoring some stuff by 1968-1970 eg Ford's 428cj got factored right away to 360hp - different for ramair and non-ramair too. But they hadn't gone factor-crazy yet.
I could sure use that Classification Guide info but not sure how to get it from you, that's a lot of info unless its in a PDF you could Email.
