Mine is 318 or 8V71 and I was under impression that all those Detroits were equipped with killing flapper like mine is?
I play with it couple of times and it works. Kills the engine in split second, but you have to manually push the flapper back on the engine.
The 1972 pusher also has engine fire alarm. Working as I tested.
Coming back to the idea of stuffing something in the intake, I am not stranger working around running machinery, but when I open back door, I have 7 huge V-belts -some turning fan blades that will take your arm in a second, other running 7 kW alternator with pulley that will not mind your leg in it.
Getting there when engine runs few thousands rpm?
No thanks.

Yes and no!
Runaways are usually caused by a busted turbo oil seal, and the oil becomes the fuel. That's why those events are so smokey. Cutting the fuel does nothing, and neither does cutting power. Cutting air is the only way to stop it, but there's no way I'd want to put myself next to an engine that could spit a piston and any moment. Plus, the damage from overspeed is most likely already done.

I was told the reason the air intake for diesel RV & trucks is up high to avoid fumes such as a gasoline spill which could cause a runaway.

Honestly, have 2 cocktails, or 4 beers, then look closely at the smoke. I swear I saw historic figures, and maybe some relitives. Or maybe that was 3 cocktails?

I'm aware of two incidents in our neck of the woods. Since the engine is using the lube oil in the sump as fuel, there's really no way to stop it, except maybe putting the transmission in Drive with the parking brake on and a heavy foot on the brake pedal. Maybe adding a pillow or a blanket over the air intake would help, but I'm not sure I'd want to be close to a big diesel that might blow to shrapnel any minute.
I've not done any research on the frequency of this problem, but it's one reason we went with a gasser.

Putting it in gear and popping the clutch may have saved the engine but wrecked the transmission and/or drive shaft.
