Block casting numbers

Need clarification on block casting numbers.
I have a block (presumably a 302) with the following:
I thought all blocks had the VIN stamped on the flat area aft of the intake manifold, starting in 1967.
This block has no numbers stamped.
C= 1960's decade
9= 1969
O= Fairlane/Torino, '67 thru '76
E= Engine Group
The 8015-C is a mystery to me, plus being a 1969 casting, shouldn't a stamped VIN appear as well?

My engine is similar in that it does not have the vin on the block. It is a replacement engine with the block number C8AE-6015-B decodes as a 302 block from the Windsor plant used in 1968 for building 289 engines. The number stamped where the vin would normally be is 8K13 76, which decodes as Oct 13/68.

This C9OE-C is a 1969-1974, 302 Windsor small-block, 2-bolt mains. The 6015 number is simply the basic part number for the engine block. I feel that there may have been some differences the start of the VIN stamping on the engines. Yours may have slipped through or just wasn't stamped.

I agree that it is most likely is a replacement block. I have never have seen a original car that was not stamped. It was a federal mandate.
