Doug,

At power settings above 65% you need to be concerned about running too
lean, thus too hot.

Uhm, no, not at all. He'd have to be concerned to run not lean enough,
actually, since the temps decrease again when running leaner and leaner.
The point is: You have to worry to run at the right point in relation to
peak.

I don't fully agree with that. The O-470 is normally aspirated rather
than injected;

Umm...it's normally aspirated vs turbocharged; it's carbureted vs injected.
