Smog Pump
I didn't want to hijack another thread so..........
Did 1972 350 four speed cars come with a smog pump?
Mine did not and the exhaust manifolds did not have the AIR Injector fittings.
Can anyone shed some light on this?

I believe that in 1972 only LT-1 cars and 454 cars were fitted with the A.I.R. pump. hope this helps

Hey, I just read my NCRS technical manual and it states "Those cars equipped with AIR systems included all LT1s, all 454 engines, 1972 base engines (200 hp) and all delivered for sale in California" I stand corrected

This has been discussed before and the 4th edition NCRS manual seems to be wrong. I think the answer to your question is no unless your car was delivered in CA.

Here is what I have on A.I.R. systems.
1970 - Chevrolet went to CCS (Controlled Combustion System) for emissions control on most Corvettes except LT-1s which used A.I.R.
1971 - Corvettes continued to use CCS (except LT-1s and LS-6s which used A.I.R.).
1972 - A.I.R. system returned for most Corvettes engines except L48s with the "CKW" and "CKX" code.
