This is what I was told today about the other number, one above the production code. It was a number used to reference the engines as they were stored in bins prior to being dropped in a car. Upon being installed on the assembly line a triangle of reference then existed between the car, the GM paperwork, and the engine. Where the GM paperwork that documents this data, may be something the general public may never know, or it just might not exist now. Maybe Jim M. could shed some light on this.
