Realistically, how many people drop $70-90k on a truck and go around with it floored at 5,500rpm with a heavy load.

More than just in a stoplight race or a burnout?
Only those that bought a 7.3 gasser to haul their 14k 5ver anywhere in the mountains, because "a diesel is too expensive and unreliable."

LOL

Show me a burnout/drag race where they can get the 7.3 engine up to 5,500rpm with heavy torque to max out the HP.

Yeah, you might be able to force it into a low gear and get up to 5,500rpm but the torque will be way below max available at that rpm. By the time you get up into the higher gears it's tough to get the rpm up that high without hitting max speeds due to wind resistance.

Reality is very few engines will ever develop the max rated HP and most owners don't want to thrash a very expensive new truck, so it's mostly about bragging rights.

I've taken 3 different GM 2500's with the 6.0 up into 5500 territory regularly in the PA/WV/VA/NC mountains pulling a heavy load, and never hurt any of them. The tachs went to 6000 in each. Let them run up into the 5's when descending in low gears also.

Wow, uphill, I've never had to go above 3500 RPM with the Ford V10. I'm betting you are a rare exception.

Of course, do it once in a great while, no it won't blow up immediately. Do it daily in commercial operation and don't expect the same longevity out of the engine.

Downhill, I've hit 4000 rpm on occasion but the engine isn't putting out any power under those conditions, so a completely different discussion.
