6150 is the number I found for the rev limiter.
Hydraulic lifters would begin to float at some point.

I seem to recall rev limiters on the Boss 351's and that to get best dragstrip times they were removed/bypassed and shifted at higher RPM's
Factory redline is another story I am pretty sure I read 5400 for the 73 Q code 4v 351

IIRC rods are good to 7000rpm when using ARP nuts and somewhat more when prepped properly.

given that my factory tach is reading 7000 rpm when the engine is turning 6200, I'd say Ford built inaccurate tach's to make drivers thing their cars were superior to the competition (and to keep us from actually shifting at redline)

"I love my Hookers!" and "Get some Strange" probably have a different connotation to non automotive enthusiasts!
