I purchased an unrestored 66 442 tricarb in 1996. I restored it and still have it. It came with some of the components for the California emissions. Namely the center carb air cleaner with the inlet tube in the base and the brass fitting that goes to the valve cover. In my research of the vehicle, I learned that it was sold by the original owner to a man in Salt Lake City around 1968 or 1969. I have seen a lot of tricarb 66's but have never seen one with the Calif setup. I am wondering if it is rare and if cars sold in Utah in 1966 would have to comply with Calif emissions?

 

That may have been the only difference in the setups. I think all that was required was a closed PCV system and the nipples on the carb cleaner bases provided that.

 

Utah did not require cars to comply with CA emissions. Also, a true CA emissions car would have had A.I.R. in 1966.

 

I have seen original CA cars with standard trans without A.I.R.. The ones I have seen with A.I.R. were automatics. I am referring to 442 models as I have not seen many other models with A.I.R. I did have one 66 Cutlass with A.I.R and was a 330 automatic. The OEM tri carb installation instructions has a picture of the crankcase requirements for CA. cars. The only CA, emission 442 or W-30 I know of was a 67 W-30 that had all of the A.I.R. equipment. It was an automatic car. Here's a picture of the 66 tri carb CA. emission page.

 

That is correct. I owned a 66 L69 in California and that is what it came with, no A.I.R. system.

 

Thanks, I have this diagram of the crank case vent system. My car was raced at the Bonneville Raceway in the late 60's. If it had an AIR pump, it and the brackets were tossed. Are these parts commonly preserved on Calif cars?
