AIR — American Iron Roadster
All of the rules that apply to the FR/GR class apply here, but the engine used must be from a production American car or pickup prior to 1973 with an iron block and cylinder head. Welding or brazing is only allowed on the block or head for the purpose of repair, so exotic port rerouting is out of the question. The only engine class in AIR is C, so maximum engine displacement is 373.99 cubic inches. Electronic fuel injection, computer controlled ignition, and data collection methods are all prohibited.
