The block date would not be correct for any '69 Camaros because it is so late. Are you sure it is not a 454 block? The 512's later became 454 blocks. I'm going from memory here, but check the bottom on the cylinders for notches as I think only 454 blcoks had these. The notches allowed the rods to clear the cylinders w/the longer 454 stroke. Dimensionally the 454 and 427 blocks are the same, just different stroke cranks. There was one on EBAY recently that was bid to ~$650. So Joe C's advise is right on. These blocks could be purchased as a short block or long block assembly. Looks like yours was a short block and someone already had a set of BB heads for it. There's no way those heads were factory assembled on your short block.

Your crankshaft #6223 is a 1970-1972 402 (396) forged steel. This has the same stroke as a 427 crank. The difference is a 427 crank is heavier due to a different counterweight design. The 427 has a 7/8" counterweight and a 396/402 crank has a 3/4" counterweight. I would say you've got a 454 block w/a 396 crank and older BB heads. the combo equals 427 CI.
