As the result of runs under the Automatic Horsepower Factoring System (AHFS) 1.20-second under policy at the NHRA Division 6 event, the following change has been made.

The horsepower rating for 73-74 Chevrolet Corvette, entries with the 350 cubic inch engine and a factory rating of 190-195 currently rated at 283, has been increased by ten horsepower, to 293 horsepower; for Stock Eliminator.

NHRA's 2019 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 July 16, 2019.
