Nikon, the reason the demon is not allowed in the NHRA is because does not have a roll cage. A roll cage is now required on vehicles going 9.99 second in the quarter and faster. We actually had to add my features to our roll cage when we broke into the 8.49 area. Plus anyone wanting to run in the NHRA has to have a competition license as well.
In the past few years all three brands have been very active in the factory stock class in the NHRA. Chevrolet came back into the mix with the COPO Camaro when it came back and Ford has had the Cobra Jet program going on since 2008. Dodge has had a few Challenger's running and have been playing catch up with the other 2 brands. Last race of the year last year there was a COPO that did 8.074 quarter and the Cobra Jet did 8.12.
