6.2/6.5 Cylinder Block Date Code

[More Power]

Hello.
The part number 10237141 for the GM 6.5-liter diesel engine cylinder block contains the following technical information:
The first two digits "10" indicates that the part is related to the engine block.
The next two digits "23" represents the model year of the engine, which is 1994.
The following two digits "71" are a code that refers to the engine application, in this case, a 6.5-liter diesel engine.
The final two digits "41" are a sequence number, which means it represents a unique identifier for the specific engine part.
Overall, the part number 10237141 provides information about the engine block's type, model year, engine application, and sequence number, making it easier to identify and replace the specific part in case of any issues or required maintenance.

Thanks for the info, but:



The above image of a GM 6.5 cylinder block casting code doesn't have the "71". And, I always thought the casting date code had it's own number on the opposite side of the bellhousing flange - either a 4-digit (GM) or 5-digit (AMG).

Interesting stuff though... Jim
