Decide my Rochester Quadrajet carburetor
« on: December 29, 2017, 10:37:58 PM »
Hi guys. I've been rebuilding my 4 Barrel Quadrajet carburetor and I noticed that I have a unique 170 code. I have been unable to fully decode the stamped code on the body of the carburetor. So maybe somebody out there has the answer? I would really like to know what the 17066558 code means from my carb as well as what size for CFM the carburetor is.

Thanks!

The code should start with 1705 (76-79) or 1708 (80's). Are you sure of the first four numbers?

6 - 1976
6 - ?? (if its a 5, its California emissions)
5 - Oldsmobile
8 - Automatic

My guess is that the number may actually be 17056558.
