That's correct. That why I referred to a COPO "block" in the title, and not a COPO "engine".

It appears from the auction write-up and comments that someone just gathered up a bunch of parts to build an L72 spec engine, and had no idea that they had used a COPO block in the process.

Why they did not spend the extra 5 minutes to find a set of date-correct 840's is a mystery.
