That being said, what’s acceptable to the aftermarket isn’t necessarily acceptable to the OEM and I remember reading something similar in an in-depth article on the development of the Road Runner ie Boss Coyote.

Yeah, luckily my friend was in town again for Thanksgiving so we talked about it. My premise was correct, but the RPM wasn't.
Turns out what I said was indeed what the engineer told my friend, but it was 8000 rpm, not 7500. The valve train is capable of even higher, but Ford lowered the redline to 7500rpm to allow a safe amount of over rev. Explains why you could get to 7900 with no issues and power to spare!
