A fella at work came into these carbs recently. I know enough Holley to know there's three vacuum secondaries and a double pumper. Two are missing primary fuel bowls. Two others are square bore, two are spread bore.

Anybody know if they have any value or what they're original to? I'm not sure where to even find numbers on them, and have no Holley books. No Chrysler linkage on any of 'em so I'm going to wager that they're all Chevy applications, but I'm not a Holley guy so I don't really know anything (not that I did anyway).

And there's a tiny Carter updraft carb.

The answers for the 4bbls are on the front of the air horn/ choke housing. Look for a LIST number and post those Your photos are terribly small. "A wild guess" on the top two is maybe 600cfm

At least one (in your hand) is known as a "spread bore" and were sold as replacements for GM Quadrajet and Chrysler Thermoquads It appears to be a vacuum secondary, and they were made in ? 650 and 850 cfm I think. No idea what they were designed to fit IE the choke hookup and throttle would have been made differently depending on "what"

How much gold?

Tons! Tons and tons of gold my friend. My guess is $20 cores at swap meet and tractor carb put on eBay. Old tractor guys love that stuff and are more of a perfectionist than car guys.
