A few years ago in CT, a group of hobbyists and businesses , were able to have legislation passed that exempted " kit cars ", formally referred to in CT as Composites, from emissions testing and requirements. This was a separate endeavor from the SEMA type legislation.

Prior to the exempt status, the only original engine that was acceptable was a documented original pre-1966 block, the cutoff where the emissions hardware etc was added to the manufactured cars. Each year as additional emissions systems were added, the emissions testing had to comply, by year of the engine block.
