I have a membership and current NHRA rulebook just as a reference for building better drag cars. What I remember as gassers and altered cars from the '60s still exist, but their classes have moved or been consolidated. Dragsters are split into Top Fuel, Top Alcohol and Top Dragster (gas supercharged or alcohol naturally aspirated) and Altereds run in T/D. Stone Woods and Cook would find themselves in either Super Street or Super Gas.
SECTION 6B - TOP DRAGSTER
Class is for dragster and open-bodied altered-type vehicles only. Altereds must have open front wheels. Full-fender and/or runningboard- equipped street roadsters or Funny Car bodies prohibited. Qualified fields with competition conducted in a dial-in E.T. format. Minimum 6.00-second dial-in; maximum 7.70-second dial-in (eighth-mile, 3.66 to 4.99 seconds).
