I should post the article I have that describes the development of an
ordinary Chevy V-6. The number of hours the engines spend at full
throttle and the torture they go through is by FAR more severe than
the FAA's mandated testing for new aircraft engines.

Attach a 6 foot propeller to the crank and everything changes. That introduces
stresses and vibrations that auto engines never dreamed of.
