Peter, this thread has grown way too long and ****y for me to go check
if you already have received this info, so please excuse any
duplication. Mike Noel hit on an important factor that did not seem to
be followed up on about a difference between aircraft and automobile
piston engines. See the papers at

Even more interesting is that Tanis leaves such obsolete information on
their web site. Take a magnet to a few car dealerships and see how many
engine blocks are cast iron these days...
