Chevrolet’s Big-Block COPO 632 Blasts Into NMCA Stock Eliminator Competition
Santa Ana, California [January 6, 2023] — Chevrolet Performance wowed drag racing fans with the reveal of the COPO 632 at the 2022 PRI Show. Combining the company’s biggest, baddest big-block crate engine with its purpose-built Camaro racer is a match made in performance heaven. However, racers need a place to compete with this competition-ready beast.
Where better to do so than with the Red Line Oil NMCA Muscle Car Nationals series? And with that in mind, NMCA rule-makers tapped into extensive test data to determine a horsepower rating and race weight for this big-block bruiser to fit within the national series’ popular Stock categories beginning with the 2023 season. 
“We were thrilled to see the COPO 632 at the PRI Show, and we immediately began determining how this exciting, naturally aspirated race car could fit into NMCA’s Stock Eliminator class,” Rollie Miller, NMCA General Manager and National Event Director, said. “Upon reviewing data on the car’s impressive performance, we found that it would fit right into Micro Strategies Stock Eliminator in the FSA and FS/AA categories, depending on the setup, and even as a natural C car in Super Stock.”
Thus far, NMCA is the only sanctioning body admitting the COPO 632 into Stock Eliminator competition, which opens up opportunities for racers and excitement for fans. Running the robust, 632-cube big-block engine fitted with RS-X Symmetrical Port cylinder heads, the COPO 632 will carry a rating of 530 horsepower and a race weight of 3,594 pounds in NMCA Stock Eliminator FS/A trim.
