Because of the time needed to construct the specialty cars for Bob Book's proposed naturally-aspirated, American 400-inch Pro Stock style class in NMCA, our sources indicated the class could debut as early as the last two races of the 2017 season, with a full compliment of events for 2016. So right now, as it stands, the Joliet event could be the first of these cars but we also hear it could be as early as Norwalk.
