Arizona emissions testing

From what I can tell it looks like they would run it on the dyno:

Besides the dyno test they do a visual check. The engine has to have all of the emissions equipment that was factory installed for the year of manufacture.

Swapped engines have to be same year or newer, and have the emissions equipment for the year of the engine that has been installed.
