Hmmmm. Going through my latest Alternative Engines Volume 3 there are a couple interesting articles from Chrysler and GM power train engineers.
The Dodge Viper engines underwent 500 hour WOT dyno tests running the majority of that between torque peak and power peak rpms. Dodge truck engines undergo a similar 800 hour validation with some part throttle and idle running thrown in.
The GM Vortec 4200 straight six DOHC engine tests were staggering in scope compared to the aircraft world. GM built 800 engines for development and testing. 24 engines went on the dyno and all met their 150,000 mile durability target. 5 of these were run WOT for 300,000 miles (let's conservatively say 5000 hours each) and all passed. GM put 4 million test miles on other vehicles validating this engine design alone. Pretty darn impressive!
Cheap powerplants:

The next guy who thinks a modern auto engine can't hack running in an airplane at 75% for 1000 hours needs his head examined.
Now we just need some PSRUs which are this strong...
