    A.I.R. Assembly

    VIN 1Z6724S412373

    Could this car have come from the factory without and A.I.R. assembly (smog pump) and a plugged manifold?

    No. No cars came from the factory with plugs in the manifold. All 73-74 vettes had smog systems.

      All 1973-74 Corvettes were equipped with AIR except 1974's with L-48, THM and federal emissions (i.e. engine suffiz code "CLA").

            That's exactly the configuration I would expect to see on a 1974 LS-4.
