In 1968 it gets a little tricky, by 1969 it's very tricky. Essentially it requires you to have any and all smog equipment which would have come on the vehicle / engine that your Cobra has in it.

This will be established by our Bureau of Auto Repair. They (are suppose to) inspect your engine and verify the origin, look up the equipment it had and verify that equipment is present. In 1968 California required many cars to have an AIR (air injection recovery) system and that means a smog pump and tubes which inject air into the heads. Many had an EGR (exhaust gas recovery) system and all had PCV valves.

If you can do some homework ahead of time and demonstrate your engine MAY not have been equipped this way they will generally give you the benefit of the doubt. Most 3/4 ton trucks (based on gross vehicle weight) and "R" code engines had the least smog control for the longest period of time. Dual carbs were avaliable here in 1968 but not in 1969.

This process involves a smog check every 2 years and the requirements are the requiremnets for the engine and year you have in the vehicle. This involves verifying tail pipe emissions, equipment verification and in my area a run on a low speed dyno. This gets tricky with large small block strokers. If your engine was a 351 you will be measured against 1969 351 Windsor standards.
