OTOH isn't there a requirement for one hour on the engine before it
takes to the air, or is that before the FAA inspection and sign off?

I've heard of the 1 hour engine run requirement, but I've never found it in
any official (FAA) or reputable (EAA) source. I am aware of some DAR's who
require it.

My DAR didn't mention it.

Personally, if I had access to a test stand with proper cooling set-up, I'd
run a new engine at least an hour. However, installed on an aircraft, and
without a test club, lengthy engine runs on the ground are not recommended
per Lycoming's new or remanufactured engine break-in procedure.
