Just lost in the Lycoming lore of " all else is

I can't speak for BOb but it's my impression that
he's not against alternative engines in and of themselves,
but alternative engines with less-than-ideal engineering
and development behind their airplane applications, and
those who are lost in the lore of "auto engines are superior
because Lycomings are old."

So far statistics appear to be on his side.
