Destroked Small Block?

I found someone who claims to have the Block of the motor from this car and is selling it for 5k

Expensive souvenir. Don't know who might be interested in such an item, eccentric collector or if it would be useful to the original car. Just a bare block, it would need some specific, verifiable markings that would identify it as specifically from that Daytona. Then, was it a test engine, spare or actually raced at Daytona. Not to devalue it if it is, but I bet the actual race engine was built to the very edge of of the cubic inch limit and any overbore would technically make it illegal. I wonder what the actual car ended up with. It has been restored. More questions!
