My project has an unusual option, factory shoulder belts. It also has tinted glass, remote side mirror, AC, PS, PB, Door Edge Guards, Power Tailgate Window, 308 posi rear, 330 4bbl engine Low Compression. Build date is 12 E. I don't know how it got California Emission heads either, the heads have plugs where the AIR tubes would go. Oh it has a roof rack as well.

 

Cool options! I wonder if it was a special order car to be sold in California? Does it have the tall oil fill tube? Any evidence, like four groove pulleys, that it had an air pump that was removed? I've come across a few 1966-67 cars with the A.I.R. setups but I assumed they were all Fremont built cars. I'm not coming up with the right term for it, but does it have the funky air cleaner that draws air off the exhaust pipe not the manifold?

This is not a CCC Climatic Combustion Control car, oil fill tube is regular length. 4bbl air cleaner is black not orange. Yes a Lansing car and It may have been a NJ car all its life. Brogan Cadillac Oldsmobile was in NJ and it had that badge on the gate but not sure if it was original. No evidence of air pump.

 

Interesting... well not what I would have expected. But maybe they've been swapped at some point in time. Or when the engine was being assembled someone grabbed the wrong heads, or whatever was handy! I wish we could go back and see exactly what happened in the life of these old cars!

 

I would think the demand for the "low compression" regular fuel 4bbl 330 cu.in. (310hp Jetfire) was pretty low
Olds may have had all the heads spec'd for the L73 engine built/assembled for use on either 49-state or CA bound vehicles (same scenario employed for the W30 heads)
everyone but CA got the plugs
- what's the engine code stamped on the passenger side head?
anyone know what the "S" above the LAN represents?

 

I will have to check that head this weekend.

I have seen different letters in that location on 67 trim tags, have not seen a decode on them however on the 67 W30 an E in that position is common.

 

Head stamping?
