Headed out to Garage to Tinker, Pm sent on Holley Tim (Dad):D

You were not specific in your PM which part you were talking about, but I see here you are talking about the Holley. Since it is a question others may want the answer to, the only other number on the air horn is 3364. I assume that's a date code.
