The attached image is from an Impala.  Casting number is 3969341 with casting date I 5 9.  Just for additional reference.  It has the C before the FW.

John, awesome photos.

67conv6cyl,

Thank You!  That does fit with the the expected original length.

The space between the C and the other two letters of the code is there for most (I am not quite sure I can say all) cases that I have seen for late 69 Model year and early 1970 model year Camaros.  It is not always there for Chevelles. 

Attached is a 1970 C OZ code that shows similar spacing.

Yes, 2 bolt and 4 bolt CE blocks.  I have one 4 bolt CE 427, one 4 bolt CE 396/402, several 2 bolt CE v396s, one 2 bolt CE 402, one 2 bolt CE 454.

I agree with Kurt, I think it is C BU.

I am starting to think more that the 3 letter code started when the casting number changed to 3969341.  But more data points are needed.

I agree with John completely. 

I have never seen anything other than the original CE stamp on the pad for the 68 model year and later. Dealers may have noted the CE assembly number on the warranty paperwork.  But that probably varied from one dealer to another.

Earlier pads were left blank.  But I am pretty sure the earlier blocks still received that assembly date stamp down on the pan rail/oil filter area.   

It has been a while since I have seen a blank pad warranty engine.

My 09C Z28/RS has the 3969341 rear, stamped BU0828

Gary, is it stamped BU or CBU?  The one Kurt posted had a casting date earlier than yours and it used the 3 letter code. 

I am just trying to see if maybe the casting date change corresponded with the change from 2 letter codes to 3 letter codes.

Thanks Gary!  

What I find the most interesting in that Tonawanda letter is the part where is says...

It should be noted that the service identification number is required in addition to date stamp markings currently put on service assemblies.

I believe the "date stamp markings" are what referred to above as "something like T097 - T for Tonawanda, 09 for month (September) and 7 for last digit of year (1967 in this case)".

If you find any other documents which might clarify this, please post those too.

Gary if you ever find that GM Directive, I would be interested in seeing it.

From what I have seen, big blocks at Tonawanda generally did not receive a letter in the CE stamp, because fewer were produced and thus in general there was not a need to reuse the numbers.  There may be some cases where they were reused but I have not seen any.

Also from what I have seen, big blocks from Tonawanda received a stamp down on the pan rail near the oil filter area, which seems to be an assembly date stamp.  This would be something like T097 - T for Tonawanda, 09 for month (September) and 7 for last digit of year (1967 in this case).  I am looking for documentation of this.  I am only going off of what I could determine from the blocks that I have.

I agree with Ed.  $750 for a Saginaw is WAY too high.  Normally they are $200 or less around here and if rebuilt and nice maybe $400.
