Carburetor identification.

[AyWoSch Motors]

So I bought a basket full of carburetors and gauges the other day at the flea market for 100 bucks. Out of the carbs. There was a Rochester 2 jet, 2 Quadrajet, and this unknown Rochester 4 barrel.
Can anyone tell me what it is, what it goes to, specs, anything?
And also anything about the 2 quadrajets?

The one looks like a Rochester 4-Jet, early 60's carb, my '64 C-10 w/283 has one. As far as the Quads go, get the numbers off the side for production dates, and numbers will help identify what they were used for or off of.

I agree it looks like a 4 jet, I actually rebuilt one last week at the shop, for a 283. I've got a lot of old reference stuff both in books and computer at the shop, so if you post the numbers I maybe able to narrow down it's production date and possibly other info.

Rochester 4 jet. Had one on my 63 340HP 409. Piece of ****. Swapped for a 3 deuce setup.
