Not sure....
But, if it runs clean enough to meet the numbers it will probably pass. I regularly smogged a '78 2F engine that was in my '74 FJ, it had almost all of the '78 smog equipment on it, and the techs always commented on how clean it was. It was not 'legal' in the sense that the CARB never knew that their was a newer vintage block in the truck, but I didn't feel bad because it ran cleanly. A 'Cruiser nut could readily tell it was a 2F, from the castings, the oil cooler, the location of the alternator, etc. but not one of the many different smog techs ever noticed and/or commented on it not being the correct engine.
If it is in-tune, no leaks in the exhaust system, EGR and gas cap function, vapor recovery system in-place and functional, and thoroughly warmed up, it will probably pass fine.
