BobT-47P15 Posted May 14, 2021 Report Share Posted May 14, 2021 One time, a while back, I discovered this date (50 5-26) on the side of a 1950 Dodge engine sitting in my garage. I had also seen a similar number on the block of an early 1949 model Plymouth. I am presuming it either indicates the date the engine was built or when it was placed into a vehicle. I know where the engine/ID number is at upper left. Do not know what the 587 or the 119729-6 to the right mean. Just putting this out to see what anybody knows about those numbers. Thanks. Bob.

martybose Posted May 14, 2021 Report Share Posted May 14, 2021 Dates like that are usually the date that the block was cast. I'm not sure what the other number is, but I would hazard a guess that it identifies the mold that was used for the casting. Marty Quote Link to comment Share on other sites More sharing options...
