Challenger makes history today

Correct me if i am wrong... But Nascar is still banning the Hemi, correct?? so the challengers and chargers have some form of a small block wedge?? cause IF they had the Hemi's it could be a repeat of when the Daytona's and Superbirds ruled, until Nascar kicked them out...I think that is when they outlawed the Hemi's..
