If I was going to buy one I would research various sources to find out what numbers to look for. There have been such threads posted here at Club Cobra for instance.

The NASCAR motors didn't have a specific number that would identify them right off. It would be more like a "series" of numbers of the various parts that make up the "package". All the "good stuff" would be there!

Also being a NASCAR engine the chances of the virgin block being a "good" block are increased. My thinking there is a little extra time would be spent in CHOOSING that block for it's "destiny" at the factory? Not all of the original 427 blocks were "good". There were some "flaws" and a faily high percentage of them were "bad" right from the factory but shipped out anyway.

Buying a "used" block today is a gamble at best. Many of them available won't be "worthy" of a rebuild. Yours being a "virgin" block increases the odds a lot, but it will still need to be checked out carefully by a machinist.

As to value? Tough call, it's kind of like buying an expensive "art" piece. It may be worth BIG money,,,,,,,or not. Heck, I don't know!
