Horsepower adjustments following the Mac Tools U.S. Nationals

As the result of runs under the Automatic Horsepower Factoring System (AHFS) 1.20-second under policy at the Mac Tools U.S. Nationals, the following changes have 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 171 has been increased by sixteen two horsepower, to 187 horsepower; for Stock Eliminator.

The horsepower rating for 85-86 Ford Thunderbird, Cougar, entries with the 140 cubic inch engine and a factory rating of 145-155 currently rated at 177, has been increased by six horsepower, to 183 horsepower; for Stock Eliminator.

The horsepower rating for 2004 Chrysler PT Cruiser, entries with the 148 cubic inch engine and a factory rating of 180 currently rated at 186, has been increased by eight horsepower, to 194 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 Sep. 11, 2012.

It is nice to see the 350 is only 81 hp. behind my 86 360 Dodge with the same cam spec's smaller intake valves and a TQ carb.
