Has to be newer than year of the truck it is going into, so that leaves 90's model engines and newer, and they have to run all of the smog systems that came with that motor, so the stock fuel injection has to stay, air pump, cat converter, egr, etc...
When I had my Fiero, I new of a guy in California that had the Caddy Northstar motor swapped, it was California Smogged, but he had to run stock computer and electronics with no error codes, even had to go as far as keeping the exhaust single outlet like the Caddy it came from, not dual's like the Fiero came with.
