What state are you in.. are you interested in just getting to pass or to be technically and legally to be able to pass ?
General rule of the law states you have to use all of the OEM for the year of the donner engine and PCM (and VIN) to match the engines year. (yes there is ways around this), same or new year engine only for the swap. You would need to use all of the Smog equipement from the Cats, EGR, AIR, Sensors, 02 sensors, etc). Your car/truck basically become and is tested as the newer car/truck that the engine came from.
Suggest you go to your states DMV web site and look for there links on Engine Swap/Conversion.

IN GA if you don’t have to pass via the sniffer test I think 1996 or newer. But as of 2009 you have to have the cats visually inspected… On my 99 LS2 Z I have a chambered muffler with a CAT heat shield welded to it…. Passed fine but the guy was about to die from fumes lol.
Also they look for check engine lights and scan the comp for codes.
The older ones back 96 sniffer test and you going to have to run cats. I’m in Forsyth as well I know some country have not emissions laws like Dawsonville. Its based of the population in the country
