The cover blurb on the October 22, 1981 issue of National DRAGSTER said it all.
1982 Rules: Pro Stock Revamped.
The NHRA decided they’d had their fill of the pounds-per-cubic-inch format which had defined the Pro Stock division since its inception in 1970.
The continual factoring of the leading Chevrolet and Ford combinations had proven aggravating at best, and controversial to say the least.
The Pro Stock division would now be based on a universal 500 cubic inch limit with a weight of 2,350 pounds.

We all take for granted that Pro Stock has been a simple formula. Today, those that participate in the class carry a common weight of 2,350 pounds in a two-door American made coupe no older than five years old with the source of motivation coming from an engine that displaces 500-cubic inches. Sounds pretty simple, huh? It has always been the nature of man to start with things in a difficult fashion and make it easier as knowledge and technology permit. Such was the case with NHRA Pro Stock as it took them nearly a decade to make the drag racing equivalent to NASCAR an easy proposition.
When the NHRA announced that they would be changing to a "mountain motor" format for the 1982 season, they were the last of the three major sanctioning bodies to abandon the small block Pro Stocks. The AHRA, whose rules had initially mirrored those of the NHRA inevitably allowed small blocks the use of nitrous oxide as they converted over to the mountain motor format a year prior to the NHRA's decision to abandon ship.
