All but a very few engine manufacturers wouldn't dream of handing you a dyno and configuration sheet to go with the engine, for fear that it would open up discussion/controversy/litigation surrounding why the engine doesn't hit the advertised number.

There's quite a large gap between advertised and reality, and quite a few less than satisfied owners who go and verify power on a chassis dyno and find a discrepency that can't be explained away by "drivetrain losses". This happens all the time.

If you want a high performance engine that truly hits the number, can be dyno'd a the manufacturer to prove it, and can be sold to you with a dyno sheet and/or video of the actual dyno work, I'd recommend shopping with one of the Engine Masters Challenge participants.

Or, one of the builders/businesses that frequent 460ford.com and have a proven track record.

Otherwise, I wouldn't buy it unless it was well known/common (like the 514 FMS crate motors), or I'd seen it run and/or had an opportunity to measure one just like it. A lot of these guys are throwing numbers around that have little basis on reality.
