CE motor stamping info

[ZLP955]

If anyone reading this thread has a CE block, and hasn't already contributed the casting and stamp numbers, please consider adding them to this thread: http://www.camaros.org/forum/index.php?topic=12873.0;all
I have a few more blocks to update that excel spreadsheet with, so this'd be a great opportunity to gather more data points. Thanks!

The 68 Z/28 that I bought s my first car in '71 had a CE engine in it.  I had the car a couple of years before it started using oil and smoking on startup.  When I tore the engine down it all the right stuff inside. It sure made me feel better knowing that I had a real Z.  Back then we didn't know what we know now.  Wish I had known more.  I pulled the engine/trans/rearend out and sold the body to build a V8 Vega.  I wasn't all bad. The Vega was featured in the Sept. 79 Car Craft

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?

Actually NO it does not make sense. The T0318ET was not part of the original CE engine stamping. I would like to see a pic.

The T089 stamping in the starter pad area indicates it was assembled in August 1969.

Crap. Right, I wasn't thinking. No assembly date or engine designation stamp on a CE block. Sorry 'bout that folks.

It would be interesting to see a photo of the stamped pad on Opelitis1 CE engine.   It IS possible that the dealership mechanic stamped the additional characters 'T0318ET' into the pad when he installed the warranty replacement CE engine in the '67-8 Chevelle (which might have been in the March 1970 timeframe ??

[69Z28-RS]

We've discussed the CE engines as 'Warranty Replacement ONLY', but reading parts of one of the original letters also implies that engines shipped to Parts Departments (for counter sales) may have also received the same type of serialized identification numbers...

See excerpt attached... with circled areas of text.  (please excuse my crude circled notations!)..     The first and second circled statements seem to state that both service replacement (warranty) parts AND replacement parts shipped to Parts Departments would get the serialized ID numbers!  And this would be in keeping with the Georgia requirement that all major components gets serialized ID numbers.   What do you fellas think?

Also, addressing the question asked by opelitis1, the 3rd and last circled statement states '... the service identification number is required IN ADDITION to the date stamp markings currently put on service assemblies.   The identification number is to be located on the area of the stamp pad that is normally used for the production date stamp.'   JohnZ had stated in an earlier post that such directives were not always followed by every part of GM... but that does allow that 'some' do, or sometimes did follow the directive to the letter (or at least as how they understood it)...

There was actually another data point contributed by a member that had a 1969-cast big block with a Tonawanda assembly stamp on the pad as well as the CE stamp. It's listed in the spreadsheet shown in reply #104 of the thread I linked to a couple of posts above this one.
Maybe it was a production engine that failed quality control (hot run test?) and needed rework, ended up back on the engine assembly line again and became a CE......

[bcmiller]

Need a pic of the pad.

[ZLP955]

Not sure when/how that data was provided, or if there was a photo. Will have a look over the holidays.
But the data on that block was-
Cast Number: 3969854
Cast Date: H 30 9
CE Stamp:  CE070400
Oil Pan Rail Date:  T099
Also stamped T0916KE on the pad.

And this second block's data from opelitis1:
Cast Number:  3969854
Cast Date: G 9 9
CE Stamp: CE060689
Oil Pan Rail Date: T089
Also stamped T0318ET on the pad.

I've seen the same thing on transmissions too (CT and trans code). In fact, I just sold one. I'll post a pic later...

[Mike S]

 I wasn't aware the transmission had a CT stamp. Was it only the major engine and transmission units that could have had the 'CE' or 'CT' stamp?

Apparently just the engine *block*, whether it be a bare, fitted, or short block   and the Transmission (and I would assume either the full transmission (or perhaps the transmission case?)..  There was almost no information in the memos re transmission details.

[ZLP955]

Mike/Gary,
CE and CT info is at http://www.camaros.org/engine.shtml#ReplacementEngines and includes this:

This numbering system applies to service engine assemblies, partial engines, fitted cylinder cases, cylinder cases, transmission assemblies and transmission cases.

[69Z28-RS]

Yes..  all the replacement parts that have ID codes stamped into them..

[Kelley W King]

For years I always heard and thought CE stood for ( counter engine ). Until I started reading CRG that is what I thought.
