NHRA Technical Department Makes Parity Adjustment Changes to the Constant Aviation NHRA Factory Stock Showdown

Based on the Constant Aviation NHRA Factory Stock Showdown performance numbers from the first 3 races of the 2022 season, the NHRA Technical Department is reducing the minimum weight for the 2019-2022 Chevrolet COPO 350 by 50 pounds, from 3575 to 3525. These rule changes will go into effect immediately. NHRA reserves the right in the future to make additional rule changes to control performance and maintain parity in the category.
