four-barrel carburetors

I'm looking for a small 4-barrel carburetor to put on my 318 and I would prefer to have another 4 Barrel carburetor like the one that originally came on the early 273 automatic cars. Let me know what you have and how much you want for it please.

Are you looking for good rebuildable carbs or one to bot on and go? I have several small avs and afb carbs but they need to be gone through.
