Any oval or road course racing I've been involved in mandated make to make engine families. They aren't like the wide open world of bracket and Super class drag racing.
However, given the mods to it, I doubt it would be eligible for most road racing classes, short of NASA's American Iron Extreme class, and the lack of a cabin cage and its subsequent bracing tells me that isn't its intended application. This is a Goodguys racer at best. Maybe they are gunning for the Optima Ultimate Street Car Challenge.
