You are looking at a Rochester 4-Jet carburetor from a 1955
Cadillac with 331 engine & automatic. The ID tag is stamped 7069071 and
dated M5. This is a core for rebuild. The secondaries are frozen. I have it soaking.
All other moving parts still function properly. Very complete. A good carb core. Even comes with the tall
bat wing air cleaner stud.
