Re: Engine serial number

One possibility is it might have been a service engine. There is a question -- at least in my mind -- as to how those were identified. Based on some weird motor numbers that people have reported I am thinking the service engines came unstamped in the normal spot. There was no uniform registration until much later so for states which registered by motor number during that era, a state (CA was one example) could specify a specific number or format to be stamped on replacement engines in place of the original number. Other states might have registered by the VN and not care about the motor number so the mechanic was free to stamp the original number on a replacement engine.

Are there any other stamped numbers you can find on the engine? Maybe someone knows where Packard placed the manufacturing ID or serial numbers on the inline engines before they were assigned a car. On V8s there was a manufacturing number that was stamped by the Utica plant at the rear of the block to ID the engine before it was in a car.
