NHRA Factory Stock Showdown to showcase Detroit muscle in Indy
Monday, June 18, 2012


From top: Ford's Mustang Cobra Jet, Dodge's Challenger Drag Pak, and Chevrolet's COPO Camaro will take part in the NHRA Factory Stock Showdown later this year in Indianapolis.

NHRA has announced the formation of the NHRA Factory Stock Showdown at the 2012 Mac Tools U.S. Nationals presented by Auto-Plus at Lucas Oil Raceway at Indianapolis, Aug. 29-Sept. 3, adding even more excitement to the biggest, richest, and most prestigious drag race in the world.

The NHRA Factory Stock Showdown is a competition designed to showcase the Ford Mustang Cobra Jet, Dodge Mopar Challenger Drag Pak, and Chevrolet COPO Camaro. The program will feature '08 and newer models. Competition will be run heads-up as a class within NHRA Stock eliminations.

“There has been a revival of sorts in terms of drag racing-ready vehicles out of Detroit,” said Graham Light, NHRA senior vice president of racing operations. “The NHRA racing community has embraced these new vehicles so to showcase these unique vehicles in a showdown format at the Mac Tools U.S. Nationals seemed like a natural fit.”

The NHRA Factory Stock Showdown adds to what is already an action-packed weekend of racing and specialty events surrounding the Big Go, a phrase coined by racers representing the significance of the Mac Tools U.S. Nationals at Lucas Oil Raceway at Indianapolis, which celebrates its 58th running in 2012. In addition to the NHRA Factory Stock Showdown, the highlights of the weekend include the NHRA Mopar Hemi Challenge, fierce competition of the NHRA Pro Mod Drag Racing Series presented by ProCare Rx, the NHRA Lucas Oil Drag Racing Series, the final race of the regular season in the NHRA Full Throttle Drag Racing season, and the inaugural NHRA Traxxas Nitro Shootouts featuring both Top Fuel and Funny Car. 

Early rounds of eliminations in the NHRA Factory Stock Showdown will take place Thursday, Aug. 30. The final four cars in competition will run Friday, Aug. 31, in conjunction with the NHRA Full Throttle Drag Racing Series qualifying sessions. The NHRA Wally will be awarded to the winner of the NHRA Factory Stock Showdown. All participants in the NHRA Factory Stock Showdown will still be able to run in the national event eliminator.
