My whole point on the auto engines reliability was that these engines
could be run all day long at 2500 RPM at full MP and last well over 2000
hrs. I guess I should have said it that way the first time. The fact that
they can be turned at twice that RPM for short periods of time is a
testament of their reliability. If you want to compare apples to apples
here, we could use the Viper 488 cid engine as an example, one of the few 
modern auto engines with a displacement approaching the GA engines. Who
would argue that this engine could be turned at 2500 RPM at 26 in MP for a
very loooong time?

I agree 100% with Ed Rosiak about lawyers being a major factor in slowing
down GA development, in fact, I blame lawyers for 95% of all the problems
in this country, but that's a whole nuther argument.
  
I also agree that volume in manufacturing has a large part to do with
pricing but, as an example, you can have a custom built V8 racing crankshaft
manufactured, and by custom I mean you specify stroke and journal size for
less than a completely stock Lycoming 4CYL crankshaft. It makes no sense.
