The engine is a Lycoming IO-360-A1B6D, 750 hours since first major in
Aug 2001

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?

Personally, with such low time on everything else (assuming all new
cylinders, etc., in 2001), I'd have my A&P put in a new camshaft and fly it
another 1000 hours or so.
