50 Vintage 4bbl Carbs for $500 - Trash or Treasure???

[bulletpruf]

So I was perusing FBMP this morning and saw and ad for a table full of carbs for $500. Owner is closing his shop and these were carbs that were removed from customer cars and tossed on the shelf. Most are in as-removed condition, but some are rebuilt. I got everything for $500 and he threw in 4 quarts of 0W20 and a few cans of brake cleaner.

I don't think I could pass up this deal; I need a Holley 4160 for the '69 Bronco, and those are $538 at Summit. Figure I've got one of those in there somewhere. I'm also guessing that I'll find one OEM carb (Q-jet, Carter, Holley, or Autolite) that will be worth what I paid for the lot.

Now I need to spend a few hours unloading and figuring out what I have.
