I'd be really curious to know what their "rules" are, if any.
I saw an episode a month or so ago where the out-of-town challengers pulled up to the line in Pro-Mods. The biggest trick for these cars is tuning them to hook up and drive straight!
Some of the newer cars (Crow-Mod and Goliath-2) are really pushing the Pro-Mod boundaries too.
The original program was mildly entertaining, but when they start Trash talking and yelling, the drama can be too much.
(but I still record it every week
