The NHRA Stock/Super Stock Committee has reviewed written requests received by Dec. 1, 2004, from Lucas Oil Sportsman racers in its evaluation of specific Stock and Super Stock horsepower adjustments and has made the noted changes. These adjustments are effective Jan. 1, 2005. Letters received after Dec. 1 will be addressed during the next review.

The review is part of NHRA's commitment to evaluating requests from the Sportsman racing community and is an important step for NHRA's Automatic Horsepower Factoring System.

Requests for horsepower changes or reviews can be writing and sent to: National Hot Rod Association; Technical Department; attn: AHFS; P.O. Box 5555, Glendora, CA 91740; or e-mail, AHFS@nhra.com.
