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

The horsepower rating for 1986 Chevrolet C-10, entries with the 350 cubic inch engine and a factory rating of 165 currently rated at 187 has been increased by eight horsepower, to 195 horsepower; for Stock Eliminator.

NHRA's 2012 Automatic Horsepower Factoring System outlines that any run of 1.20-second or more under the index will receive an immediate index decrease or horsepower increase. These changes are effective Oct. 8, 2012.
