This is a good starting point... the Nostalgia Super Stock class is alive and well. I was close to the guys from http://www.422motorsports.com when I had my 64 galaxie together and running. Those guys are a wealth of information (east coast guys from NJ area). They have cars from ford/chebby/mopuppy and don't discriminate so long as the cars are fast AND N/SS legal. Many of the cars are original factory lightweights OR restored original drag cars from the 60s... Super cool gang of racers...

Permanent class designation must appear on your windshield prior to entering the staging lanes. Drivers will compete in heads-up trophy class run-offs and in an all-run dial-in cash eliminator.

Cars will run on a Sportsman Ladder (1-5, 2-6, 3-7, 4-8, and so on) beginning with the second round of cash eliminations. Competitors are not eligible to compete in any other categories, regardless of e.t., except Gambler’s races.
