I don't think the configuration/components of any of the broadcast sheet used 3-digit engine codes have ever been shared based on information found on any Chrysler Corp. documentation - AFAIK all decodes are based on "reverse engineering" the codes based on the vehicles there are found within

"WE" assume it's the last 3-digits of a 7-digit assembly part number - I've never seen any of the 7-digit numbers shruggy
