CE motor stamping info
« on: December 16, 2018, 06:28:24 PM »
There's been a lot of discussions about the letters after the CE code, e.g. CE9A45361. I happened upon this page in a pile of documents.

Thanks for posting that Kurt! Would you think the letters denote the items/assemblies in the same order as listed in the letter?

Thanks for posting this Kurt,,,,,,, "Jim" aka CE9A49906
Funny they do not stamp them with the gap between the CE & the serial number

Actually it IS a serial number; required by GM for the replacement drivetrain (Eng/Trans) components!  It's a 'serial number' for the CE engines, and GM was prompted by the government to serialize the replacement engines/transmissions due to an issue originating with the state of Georgia.

I posted AN EARLIER GM document related to CE/CT serials here in CRG several years ago...   I learned about it around 25-30 yrs ago.  Here is that earlier thread re CE engines including the Aug 1967 document I posted at that time..

Gary, it is a serial sequence number and just because you are older than me - it doesn't mean you have to disagree with me.  And it doesn't me mean that you are always right. :)

Serial number usually means it can be tracked back to a specific assembly (think paper money, firearm, etc.)  Not completely true in this case. There were probably some internal records, but those are likely long gone.

If you are going to constantly nit pick every single post I make, it's going to be "not fun" for either of us.

FWIW, I have pics of pad stamps with the letter A after the year up to 1973 (CE3A57896), 1972 and 1974 stamps that use an N (CE2N23010 and CE4N23342) and what could be a 1977 stamp that is CE7P28022.

CE4N23342 is a large journal forged crank 327 short block that I own.

I also have a pic of an engine stamped CEA135856 - which may be an error since the A should probably be after the 1.

The document clearly reads "Serial Number".

You can bet "they" GM & the plants & divisions "USED" (Who cares How),,,, that Serial Sequence Number for sure.

Bryon,

It's not 'nitpicking' when someone corrects you.   You made an incorrect statement, and in this site we all TRY to be as accurate as we can...  That's all...

And I cannot help it if you have fun being wrong..  :)

Sorry, but I would have corrected that too. It's a serial number. Not sure if GM kept records for very long on them....

Yeah, it was a lucky find. Wonder what happened to CE9A50000 to CE9A89999, etc? Maybe those were assigned to the other engine plants?

Tomorrow (17Dec2018) is also the 245th anniversary of the Boston Tea Party (17 Dec 1773) one of the events that precipitated the Revolutionary war.

The CE code sequence that was stamped into warrantee replacement engines (and CT in trans) WOULD have been stored in GM's records in order to accurately assess further warranty rights of the car's owner (in case that replacement engine/trans needed repair) during the remainder of the warranty period.

IIRC the original issue re the state of Georgia had to do with insurance and title issues in the event of a stolen car...

I have a 3969854 block with  CE 060689 T0318 ET on the front pad..      Starter pad reveals  TO89  .
G9 9 is found on one side of the block in raised letter / numerics. 
Does this make any sense within the context of this posting?

Yes it does. It's a warranty replacement 396/325 (with a Turbo 400) for a 1967 or 1968 Chevelle, and was assembled on March 18th, 1970.
