I'm not sure where this came from....

 

Looks like a 4GC...but need some numbers to get it closer...

 

Looks a lot like a Carter AFB to me.

 

I agree with Yellowstatue, the 4 jet preceeded the quadrajet on Oldsmobiles. So it may be an early to mid-1960's but without the application tag I don't know if the i.d. can get much closer than that. John

 

I vote for Roch. 4GC, except for the coil type choke stove like the one that came on 65's

 

Looks like a 4Jet to me, thats what came on lots of gm's before the Qjet.

 

I believe that's a Carter WCFB from about 54 to 61.
Joe will know for sure.

 

This is 100% a Rochester 4GC carburetor. The data tag with the carb number is missing so it is nearly impossible to verify what it came on. The PCV valve adapter looks like the one that Chevrolet used on the 63-65 283's 220 HP, and the 63-65 327's with 250 HP.

 

This is definitely a 4GC carburetor. It was used up to 1965 in various GM vehicles and then replaced with the Quadrajet.
By the looks of the PCV fitting and the orange paint I would say it came off a Chevy.
