As the result of runs under the Automatic Horsepower Factoring System (AHFS) 1.20-second under policy at the Woodburn event, the following change has been made.

The horsepower rating for 1978 Buick Regal, entries with the 231 cubic inch engine and a factory rating of 150 currently rated at 160, has been increased by seven horsepower, to 167 horsepower; for Stock Eliminator.

NHRA's 2017 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 Sept. 18, 2017.
