If I may be forgiven (or not) for reading about the Corvair crank
failures with rectal vision, they should not have surprised anyone.

If you would read the site again, I think you will find that the breaking
problem is limited to higher speed airplanes, not stuff like aircampers,
right?

It is highly unlikely that any auto manufacturer is going to put
a crankshaft that is a whole lot stronger than needed into a
standard engine, don't you think?

Some manufacturers, at certain times in their lifespan, are less comfortable
with cutting design strength margins too closely. GM is more likely to
build hell for stout, than are many of the imports, IMHO.
