Correct Holley 3367 Secondary Fuel Bowl

[Ralph J.]

I have a 1966 327/300hp (late '65 build), and I'm trying to determine the correct secondary fuel bowl for my 3367 Holley with date code 5 9 1. Should it be with or without the volcano? Mine currently does not have the volcano but I'm not sure that is correct.

Thanks,
Ralph

Ralph,

Are you talking about the air vent on the front bowl, as shown on this 3367?

I'm referring to the rear float bowl with the word Holley on it. Attached is a picture of the rear of my carburetor.

Ralph,

Search as I might, I can’t find what the “volcano” is that you’re talking about. Can you provide a description or a photo.

Gary,
I'm sorry I guess I should have been a little more specific. Attached is a picture of a secondary fuel bowl with the round hole next to the word Holley. I've heard it referred to as the volcano. I just can't determine if it should be on my carb or not.

Are you sure it's not actually the name used for the feature on underside of the bowl, below the blank hole?

[Ralph J.]

I was told my rear bowl was missing the circular hole to the left of the word "Holley" as in the attached picture of just the bowl with the #3 label on it. I'm just having trouble verifying whether or not it should be on a Sept 1965 dated carburetor. My car is a 1966 327/300hp built in approximately Oct 1965.

I'm sorry I don't know.. I see that the holes are there on the 4150 Holley for 65 L76, L79 cars.. I don't see it on any 3367 Holley for 66 300hp cars. Hopefully someone will speak up to answer your question.

Ralph, I am thinking yes your carburetor should look like the pic with #3. The later replacement bowls look like your existing secondary bowl.

[Ralph J.]

I'm thinking that it should have it as well but I need to confirm it before i make any changes.
Thank you all for your input and help.
