Identify early bbc smog stuff......

[Terry F.]

Need some help identifying some 67 big block corvette smog hoses. Recently, there was a picture posted of a 67 bb with a smog set up on it. It prompted me to dig out some stuff that I had not identified. If someone has a clue about it, please let me know. What have is this:

One diverter valve that has a GM33547 samped on it. It may have more numbers but there under the hose.

Hose leading from the diverter valve, about 1 foot long, three ribs, no part number that I can see??

Hose GM3889379RJ (not sure about the 9, could be an 0). I believe it went to one of the gulp valves.

hose 8902340UA GM or 3902340UA GM. I can't tell if the first number is an 8 or 3??

There is a "Y" shaped gulp valve and a standard gulp valve and a passenger side exhaust injector tube. About 4-5 tower clamps dated 1/67. All nice stuff. Help would be apprecitated. Thanks, Terry

The mixture control valve (diverter) valve identified by number "33547" is a 1967 Corvette with 427 and K-19 piece. The complete part number, usually not found on the valve, was GM #7033537. However, this valve was also used for 66-67 passenger cars with big block.

The hose part numbers of GM #3889379 and GM #3902340 are not the part numbers I show for a 1967 Corvette big block with K-19. Part #3889379 and 3902340 were used for 1966-67 and 1967, respectively, for passenger cars with big blocks.

So, I'd say what you have here are K-19 parts from a 1967 passenger car with big block. However, as I mentioned, the mixture control valve (diverter) is the same as Corvette.

Cool! I assume the air tubes that feed the intake are same for passenger or corvette. I saw a picture of them and they looked identical. Thanks for taking the time to do that. Best regards, Terry

The manifold pipe assemblies are the same for 66-67 passenger and Corvette with big block.
