67' Corvette smog/air car

[William O.]

Question:

Were all 1967 California cars Air/Smog? there is a listing on Ebay item: 4599453434, that does not have air, is this correct? or were there any exceptions?

All 1967's originally delivered to California were required to have an "exhaust emissions control device". For Chevrolets and most other cars this meant an air injection reactor system. I don't think that any other system had been developed at that time that would meet the requirements.

For 1966, there were a few exemptions, although I don't know how they were arrived at. For 1966 Chevrolets, cars equipped with the 4 cylinder 153 cid engine, the L-78 in Chevelles and the L-72 in passenger cars and Corvettes were exempt from the California exhaust emissions control requirement. No such exemption existed for 1967, though.

I expect that the car on eBay, if it's an original California car, has had the A.I.R. removed. Many systems were once so-removed.

That car's only issues are not limited to missing the smog system.

Thanks Brian:

It looks like a fine car.... but with a lot of questions.

Re: 67' Corvette smog/air car

Joe - have you ever found documentary evidence that there were "exemptions" for some 1966 engines. I know of none.

The CA standards for '66 and '67 were not that severe, and it's possible that some engines were certified without AIR.

The '66 L-72s did have ported vacuum advance, and there would be no other reason to configure the vacuum advance this way other than emission control.

I've never found documentary evidence that an exemption process existed within California regulations for the 1966 model year. However, such an exemption process must have existed. There would be no other reason that I can see that the 153 cid 4 cylinder, the L-78, or the L-72 could have been exempted. Certainly, these engines would not have performed better emisssions-wise than other engines. In fact, I would expect that the L-78 and L-72 would have been among the worst for emissions.

Threre is really no practical way that I know of to research the "fine points" and "details" of emissions regulations circe 1966. All of the references that I've found omit "previous revisions" and "obsolete regulations". Such information may still be out there, somewhere, though. For me, it's not worth further effort. I'm very satisfied that there had to have been some sort of exemption or exclusion for these engines. 1966 was, more-or-less, a "transition" year for exhaust emissions control; for 1965 there was none required and for 1967 it was required pretty much across the board. So, it makes sense that there may have been some kind of "exemptions" or "exclusions" built into the regulations for 1966. Having been involved in governmental environmental regulatory work for 33 years, I know that's the way these sort of things often work. Very often, the "exemptions" or "exclusions" are based upon rather arcane protocols, and I expect that's very likely the case here, too.

Now, that's something that I would not DARE get into with him. "Smog" issues are one of the absolute NO-NO's when engaging Ken in discussions. This is a HIGHLY EMOTIONAL issue with Ken and that tends to obscure his rationality on this subject. It can be likened to putting raw meat in a shark tank.

Bill -

The auction also states that the A.I.R. system has been removed, and the engine is wearing the correct "JA" suffix and sticker for an A.I.R. car; another opportunity for Bill Hodel
