If those are prices listed in the catalog, the "partial engine" under part number 3970657 cost $878.00.  My receipt shows a list price of $632.50 for the block and they were charged $543.63.

Jerry:  This is a great resource.  Thanks!  I was able to match up some of the numbers from my receipts.  For example, the part number for pistons #3946876 match for a '69 302.  The valves #3849818 designate a Z28.  Unfortunately, I was not able to find the part number for the block.  My receipt from 1974 shows part number 3970657.  That's close to the number for a '69 302 "block assembly".  The number for that is 3970647.  But, the description says that the assembly comes with pistons, rings, etc.  My receipts have those items broken out.

"You can't tell without seeing the inside or measuring the displacement."

That's what I was afraid of.  We have the sales receipts from 1974 that list the part numbers for block, pistons, etc.  I called the GM Heritage Center to see if they could look up the parts number in the old GM parts catalogs.  The guy tried to help, but the 1974 catalog didn't even list parts for a 302.  He was not able to find the part number I gave him for the block.  I wonder if there was a Performance Parts Catalog in 1974?  I know that the receipts don't replace an engine stamp or seeing inside the engine.  But, I hope they at least give us a reason to keep digging.

OK, thanks.  I think we're getting closer on the CE code.  It stars with "CE", then comes the production year (not the model year), followed by the letter "N", and then a five-digit number.  We're planning to sell the car and engine.  The challenge will be convincing the potential buyers that this is, in fact, a replacement 302 without digging too deep into the engine.

...unless the "CE" code replaces then Engine Code and not the partial VIN, if I had it backwards.  If that's the case, how can you identify that the engine is a 302 and not a 350?

Paul, thanks for the response.  I did read that.  It's a little bit vague in that it explains the numbering system for the partial VIN on a replacement engine (at least in 1968).  But, it didn't say that replacement engines don't get Engine Codes.  Also, that bulletin is from 1968.  It looks like the numbering system changed between '68 and '74 when our replacement engine was purchased.  The partial VIN still starts with "CE", but it's not a model year and sequence number after that.  It looks like the production year followed by a combination of letters and numbers.

We have a 1969 Z/28 project car and I am trying to confirm the engine.  The original engine was blown.  A replacement 302 was purchased in 1974.  The Block Casting appears to be 3970010.  We can read the partial VIN on the engine pad, and it starts with "CE" as we would expect for a replacement engine.  There doesn't appear to be an Engine Assembly Code to the right of it.  Were replacement engines stamped with Engine Assembly Codes?  Thanks!
