Horsepower adjustments following the NHRA National Open event in Atco, NJ

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

The horsepower rating for 87-92 GM SS/GT, entries with the 305 cubic inch engine and a factory rating of 185-210 currently rated at 241, has been increased by eleven horsepower, to 252 horsepower; for SS Eliminator GT only.

NHRA's 2012 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 May 7, 2012.
