Note here from the Chevrolet Dealer Service Information Bulletin dated September 29, 1969.  It is the same wording used in the CRG engine section for CE engine coding.

The last five digits specify the service replacement unit sequence number.

There was discussion a while back that this was a "serial number".  I did not agree with that wording, and I still don't agree with it.

The right hand side column header in the extract you posted is 'Serial Sequence', the sequence (range) of serial numbers assigned to each engine plant.

The wording "serial number" to me suggests something is trackable forever.  Obviously that is not what happened with these assemblies, or we would have tons of dealer replacement paperwork matching up with these blocks and transmissions.

I have not found any documentation that uses just the two words "serial number" to refer to them.

It is a number. It is serial. But not a serial number.

We may have to agree to disagree.

Disagree away. But not sure why this seems to be so important to make a distinction. Trackable or not, the bulletin set out a sequence of serial numbers that were part of the CE stamp.

Funny!   Bryon doesn't think it's a serial number..  even though they were 'built serially', and have a unique number assigned to each part which is a part of that 'series' of numbers.   Even the original GM document refers to them as 'serial numbers', noting that the state of Georgia required unique 'serial numbers' for each of these major parts/assemblies.

Trackable?  I'm sure that GM 'tracked' the serial numbers during the period it was critical to them (the warrantee period), and perhaps after.  Since the purpose of the entire CE/CT documentation and serializing was for 'theft' purposes, it was probably up to the owners of the vehicles to maintain records of warranty replacement parts installed on their cars to be effective for that purpose; at least it's true for that today since we apparently don't have access to the original GM 'trackable' information.

Attached below is a copy of the original GM internal letter creating this system which refers to the identification numbers as 'serial numbers'.

With all respect to Bryon I would call it a serial number because there should be no two alike even if there is not a way to track them. "part numbers" can represent thousands of the same, but serial numbers should one of one.

Has anyone seen a previous year casting style block used as a warranty block for the next model year? My 2657 casting, which was for 1967 model year, is stamped as a CE8XXXXX, with an assembly date stamped on the starter area of 08 7 F...... seems unusual to have been assembled that early for the 68 model year. Did they use whatever castings were leftover?

Barry yours was assembled at Flint in August of 1967, for the 1968 model year. We donít know when in the month it was assembled. The older castings were probably being used up as the new castings started. There is always some overlap, which varies.

What is the casting date?
