Just the '78-'79 SC's had smog pumps (all markets I believe). '80-'83 had three way cats and no smog pump.

For the CA market, '78-'79 had a special smog setup that included the smog pump as well as a CA specific computer and a EGR valve that required a CA specific intake manifold.

I'm not certain about the '74-'77 middies, but I think '74 was a good year, no cat and a good exhaust setup. '75-'77 had thermal reactors and smog pumps.
