I wish Chrysler would submit all the specs for the production Challengers. It took them several years to get the 5.7L and 6.1L engines in the Classification Guide for the non-DP Challengers. I think they could put the V6s in there in case someone wants to run lower classes.

As for the Hellcat, SS/AAA has a weight break of 5.0 pounds per HP. That would make the car weigh 3535 pounds. I bet that the production Hellcat Challenger can get down to that weight. I'm not sure there is value in putting that engine in the DP.
