Yes, as stated, there's a big difference between an engine that will "rev" to 7000 and an engine that "peaks" at 7000. You can take an engine that peaks the horsepower at 6000 and it will probably spin 7000 if it doesn't float the valves, but it will probably be down 25-30 hp by then as well.
I'm reminded of all the guys who had the 289 Mustangs back in the 60's.... "That 289 would spin to 8000 with no problem." Yep, it sure would, but it probably quit making horsepower about 2500 rpm ago.
But yes, that's why we all clarified our statements about where the engine peaks and what to expect there.
