The birth of Pro Stock as a drag racing class is one of the clearest examples of mechanical evolution in racing. Starting in the early 1960s when the Big Three started funneling money into drag racing programs and promotion, Stockers got quicker, faster, and crazier. The great mechanical minds that populated NHRA Pro Stock when it was officially created in 1970 drove performance year after year, and by the end of the first season, it was a craze.
This video has cool (and rare) interview footage with Bill Jenkins and is totally full of awesome in-car and out of car tape of stockers and pro stockers being worked hard. Our personal favorite is the in-car footage of Jenkins bangshifting with a stogie in his mouth!
