Re: V8 Piston damage what do you think happened

...from the limited pictures seen, this looks like classic detonation damage.

I would agree except that the damage is confined to lowest portion of the piston where a liquid would settle and it looks like chemical corrosion though having been cleaned up kind of eliminates some of the evidence. And I would have expected detonation damage more towards the center of the piston - does detonation damage usually localize at the piston edge? I've no experience seeing it on a Packard V8.
