You are bidding on a used Rochester 4GC four barrel carburetor from a 1964 Chevrolet 327 cubic inch 250 horsepower V8 engine, I.D number 7024121.  The carb is complete, and the throttle plates, adjustment screws, and other linkages move freely.  Due to my being away at a swap meet when the auction ends, this item will be shipped out on Monday, April 29th.  Happy bidding!
