750HP / 580TQ puts peak power at 6,791 RPM
I would believe the second to be truer for that vehicle and engine configuration, so it can and often does…

This is not necessarily true. Each peak can and usually does occur at a different rpm. Your math above assumes the HP and Torque numbers are peak values occurring at the same rpm.
So 750 HP peak may occur at 8,000 rpm where torque has dropped off to 492 lb ft.
While peak torque can occur somewhere lower than 8,000 rpm.
