In California your injection technology must me equal to or newer than what came in the vehicle originally. So if your Ranger has EFI, you simply cannot have a carb. And as far as I know the motor cannot be more then 4 or 6 years older than the vehicle it is being swapped into, but that I'm not sure of.
Also, in doing EFI, you need all of the smog equipment that came on that vehicle. So, say you got a 302 out of a 91 Mustang, you need every smog component that came on that vehicle in 1991. Now you must take it to a smog refferee. They basically look over everything carefully and judge wethere or not its road worthy, done correctly, and if all of the smog is there, and how well the motor runs. Then it is to there judgement wether they pass you or not. If you do get passed, they will give you a slip that you take to the smog station that says they smog it as a 1991 Mustang.
