Pontiac flathead engine date of manufacture

Recommended Posts

I just bought a Pontiac flathead 6 engine and I was wondering what the year year it is. The casting block number is 6-315217. I'm also looking for a water pump.

Thank you.

6-315217 is not a casting number. it is a stamped number. A stamped number is probably the engine serial number.

The second picture shows a casting number 489000.  A casting number is always raised.

According to the engine number lists in The Standard Catalog that engine is 1937. About halfway through the run. I expect there might be a casting date on it somewhere.
