Am I the only one here that finds that appalling? An IO-360 is generally
considered to be one of the most bullet-proof engines ever built -- what the
heck caused the cam to spall so quickly? With over 15 hours per month of
usage, it's not like the engine sat unused for very long -- so you should
have had plenty of lubrication on those lobes.

Who overhauled it *last* time?

I think that's probably not a relevant question. Chances are the can was not
replaced. It was inspected and found to be in tolerance. Most owners with an
in-tolerance cam will elect not to replace it.
