Looks like a 3310 vacuum secondary.

Holleys usually have there part number listed on the wall of those primaries if i remember correctly

 

Thanks will double check figured they had to be somewhere

You can get the list/part # off the air horn and research it and tell what it is. It will help you sell it it if you know what it is. It looks like a vacuum secondary unit that's good for the street.
