Hi Everyone,

Anybody know what 16347 stamped in an 010 CE block under the starter flange and on each end of my original 186 heads decodes? The pad is stamped CE9B46015 and the date code looks like I 27 9.
 
Thanks

This is an old post I'm responding to, but I was searching for something and came across it...  Smiley

'I suspect that 16347 number stamped into the heads and block represent a 'customer number' from a machine shop doing work on the engine.'

I found interest in the CE9B46015 (date I 27 9) block as well, as I own a '69 Corvette unrestored original (40Kmiles) which got it's engine replaced under warranty within it's first few weeks of life.   It's a August 7, 1969 car with the CE engine notated:   CE9B44296 (date I 18 9), which is 9 days and 1719 CE blocks earlier.   

That's seems to be a LOT of CE replacement engines in only a bit over a week!

There seems to be a lot of discussion about the CE numbers. I had always thought that after they went through all the A's the went to B. I just read some where that A was short block, and B was long block. Can anyone confirm this?

We dug out some original GM literature a few years ago, which addressed the way the CE numbers were assigned... I just have to recall where I stored it.   I *think* I remember that the letters were just another trip thru the numbers they allotted..  ie..  no letter, then A, then B...   ?  but I might be mis-remembering this.

The A in the CE0A sequence is a code used at Flint to indicate the type of assembly built A=short block. The 010 block was used since that was the block in production at the time of replacement and matched your application. The sequence numbers at Flint started with 20000 placing yours as # 9422 in the sequence.  CE=Chevrolet Engine, 0=1970 production year, A=short block, 29422= sequence number 9422.

This was in response to the numbers I gave Pat about my CE engine.  B signified something like block with pistons and C was like just a bare block. A was a complete short block.

A question concerning warranty replacement blocks.
 Did GM require a bare block replacement to originate through the sources in order to be stamped with the appropriate CE?C markings? What would prevent, or was it possible for a dealer to replace a bare block under warranty with maybe an unmarked bare block sitting in their parts inventory?
At the time did statutes require the replacement block to be stamped by the dealer's service department?
Thanks,
Bob

I've studied "CE" block stampings for many years, and have accumulated a sizable library of "CE" stamp images from Camaros and Corvettes while doing so. My research indicates that a letter ("A", "B", etc.) following the year of manufacture digit indicates a second ("A") or third ("B") trip through the originally-assigned block of "CE" numbers, and Flint V-8 was also later assigned a supplementary block of numbers (90000-99999) in addition to their original block of "CE" numbers (20000-49999).

The "CE" replacements were furnished as both short blocks and as "fitted" blocks (block and fitted pistons, no crank or rods), but the vast majority were short blocks; it was rare to blow one up and not damage the crank and rods.

The "CE" block in my '69 Z/28 was dealer-installed in June, 1970 (using one of its original 186 cylinder heads and one new replacement 186 head with screw-in studs and guide plates), with all the original bolt-on parts (intake and exhaust manifolds, A.I.R, alternator, distributor, etc.). It's stamped "CE0A96509", in the supplementary block of Flint numbers.

Thanks John...  for affirming my *memory*.. Smiley      on another auto board (Vettenet? or ?) several years ago, someone posted the original GM directive concerning the 'numbering/labeling' of replacement warranty blocks, and what you desribed is what I remembered it saying.. and tried to say myself earlier.. Smiley    somewhere, probably on an older computer disk, I saved that document.... but there's no telling how long long it would take me to find it..  IF that old computer still works..

John, my 70 Z28 project has a ce block in it as well. I can send you pics if you need them it is stamped CE0A959 23. The dealer didn't even paint the short block when installed. It was cast E90. The car is an 04D car, so it didn't last long. It is stamped 5 70 by the starter. The orig 186 heads were used. The engine is at my engine builder and he states that it doesn't have floating wrist pins, and the cam is way bigger than it is supposed to be. It is a gm cam, and I don't believe that the engine was touched after the short block was replaced. The orig owner took the car off the road in 1977-78. It has not been driven since. Would the flint guys use what ever was on hand, or was this a Friday short block?

"CE" short blocks were ordered by part number, for each particular application - yours would have been the common LT-1 short block shared with the Corvette; most were built on weekends in batches, as they had to be handled manually onto pallets at the end of the engine assembly line with no heads, intake, or exhaust manifolds. The only GM solid-lifter cam "bigger" than the LT-1 was the "30-30" - what are the numbers cast into the cam core between the lobes?

  Were CE blocks ordered to match the original application such as 2 bolt CE to replace a 2 bolt original vs. 4 bolt CE to replace a 4 bolt original block?
So far all CE blocks in general I have seen were all 4 bolts.

The four bolt ones were the ones that got beat on! John, I will make a call to my engine builder and get the numbers. Didn't the LT-1's have floating wrist pins like the 302's?

I don't recall offhand - I don't deal much with Corvettes built after 1967. :-)

Nope, LT1 was pressed pin
