Post a few pics of it, namely the top and left and right sides. What kind of engine is it off of?
EDIT: After 30 seconds on Google (search term: Quadrajet Identification), I came up with this: It's a 1979 manual transmission Pontiac carburetor. To extrapolate further, logic follows (guessing here) that it likely came off a Trans Am with a 400 and a 4 speed. It would be a 600 cfm carb most likely unless it has a shortened stop on the secondary air valve door shaft.

GRRR... Another source is now saying it's a Chevy truck carb used from 78-85. I should go look at mine as it is off a 1979 Chevy van with a 350.
Looked at mine... it's 17080513 3379 CRY

But the 065 tells the rest of the story. The 0 does not conform to what is seen in the article I saw (1bbl Monojet), but seeing as both his and my carbs are off light trucks and not cars, it may be that it is a variation used for those applications. The 6 means it's a Pontiac though, so possibly the 0 should be disregarded? The 5 is what designates it is a manual transmission carb. Had this number been even, it would be from an automatic trans application. This is all what the data I found with a quick Google search seems to indicate. The 1439 is a date code corresponding to the 143rd day of 1979, and the CTH is the application code that I can't yet find the translation sheet for. It sucks too since I used to have it bookmarked before my hard drive crashed and took all of my saved Quadrajet data.
Oh, one more thing to help clear this up: does the carburetor have the straight in (points at the radiator) fuel inlet, or the 90 degree fuel inlet (Points at the passenger's fender)? Typically (from what I remember), only Chevy and Cadillac applications use the 90 degree inlet while all other GM applications (Ford and Chrysler used them too at one time or another) use the straight in inlet. The straight in is harder to plumb in a Chevy because it comes too close to the water neck in the intake manifold. Of the three Quadrajets I have had on my 350, one was a Buick application when new and it was a PITA to plumb. I later changed it to the one I have now after a 5 month search for a good one off a 350 without worn throttle shaft bores in the base plate. (the other of the three was the proper E4ME electronic Quadrajet off a 1984 L-69 305 Z-28, but I got rid of the computer to make tuning easier).
whats the size and hp of the engine you're going to be using the carb on?...a 600 is good for at least a 350 hp engine. A carb that's too big for the application kills the performance
