After seeing the beginning it was shown a while back. I caught the burnout contest at the end of the show when I saw it, now I've seen what I missed. the cars are Chevelle, Mustang, GTO Judge, Hurst Olds, AMX 390, Buick GS, and Challenger.
There's also another challenge shown after this with Trans-Am racers, which may be a repeat as well.
They're gonna do one more run for those that wanna check it out or missed it starting in an hour with the Muscle Car Shootout and then the Small Block Shootout(Trans-Am racers) right after. This is starting at 1AM Central time for myself (2AM ET).
