re: "Despite the above it is really hard to run the engine in any reasonably

Not necessarily. I run WOT for up to 10-15 minutes at a time pulling up some
very long, steep grades (up to 16% according to the signs). There are quite a
few of these in the Sierras and Rockies. That's my 'rolling road' dyno.
WOT with a full load up a steep grade--sometimes with O/D, sometimes I have to
drop into straight 4th or even 3rd--if the engine was going to knock it would
do it then.
On really steep grades I have to run my Mustang GT--315HP--at or near WOT for
several minutes (esp. if I don't downshift).

A properly tuned BJ8 will reach 100 MPH in 20 seconds or less on a flat road at
full throttle!!
Race cars get a better chance but even they seldom run at full throttle for
very long.
If you really want to experience the effects of poor or incorrect fuel or
prolonged detonation on an engine put it in a boat.
Don't ask me how I known:-(
