CE engine code with assy date

[ssl78]

This engine was taken out of a 68 Z over 20 years ago. This is a service dated 1969 engine but has a ssy date with a MO code on it. I was wondering if any one has ever seen a CE engine with a assy date and code?

It's essentially guaranteed that the 'assy stamp ....MO' was hand stamped by either the car's owner or the dealership performing the warranty replacement (at the owner's request most likely).  The engine plant did not do application stamps with the CE stamps.

PS.  If I'd been the owner of the car with the engine being replaced, I'd have asked the dealership to add those stamps as well...   as most would who knew enough and cared enough about the originality of the car.

I agree with Gary.

Thanks that is what I was thinking to denote it was a 302 engine. Thanks

The stamping is no guarantee that it’s a 302.

This time, I agree with Bryon.   

The hand stamped 'MO' code is NOT a guarantee that it's a 302.   To be *more sure* that it's a warranty replacement 302 short block, you'd have to disassemble at least enough to verify the internal parts are 'factory 302' parts!  ie.   crank at least, and the rods, and pistons if you took it down that far.  If it was an unmolested 302 short block CE engine it would also have the factory numbered 302 camshaft.   If the block has all that, it would provide good confidence that the CE engine was provided to replace a 'blown up' 302 under warranty.

Without confirming the internal parts, your CE engine could be a replacement 350 block that someone (later) stamped with the 302 assembly codes to 'fool' others.
