If they register it as a 2006 then it must pass emissions for a 2006. If it has an older block and you want it to pass emissions on the older block, then you must go the reconstructive vehicle route. Some one bought an ERA Cobra from ERA's secretary and registered it in NJ. They had no problem registering it as a 2005, but the engine was a 1975 block. It had to pass 2005 emissions, which it could not without cats and probably fuel injection. It turned into a real mess!
