As the result of runs under the Automatic Horsepower Factoring System (AHFS) 1.20-second under policy at the NHRA Carolina Nationals event, the following changes have been made.

The horsepower rating for 88-89 GM Camaro/Firebird, entries with the 350 cubic inch engine and a factory rating of 225-230 currently rated at 270, has been increased by twelve horsepower, to 282 horsepower: for Super Stock Eliminator.

NHRA's 2022 Automatic Horsepower Factoring System outlines that any run of 1.20-seconds or more under the index will receive an immediate index decrease or horsepower increase. These changes are effective Sep. 27, 2022.
