As the result of runs under the Automatic Horsepower Factoring System (AHFS) 1.20-second under policy at the NHRA Division 3 events, the following changes have been made.

The horsepower rating for 88-92 GM Camaro/Firebird, entries with the 305 cubic inch engine and a factory rating of 170 currently rated at 210, has been increased by seven horsepower, to 217 horsepower: for Stock Eliminator automatic.

The horsepower rating for 1987 Chevrolet Caprice, entries with the 262 cubic inch engine and a factory rating of 130 currently rated at 140, has been increased by five horsepower, to 145 horsepower: for Stock Eliminator automatic.

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 Oct. 10, 2022.
