If you read the article, that's exactly what happened. They put the engine on a dyno at max power for 300 hours included repeated cooling to 20 below and heated to 235 degrees, then installed in an F150. That truck was then put to work towing 11k pounds, towing Richard Petty's racecars around Miami Speedway for 1600 miles (averaging over 80mph), and several other real-world testing scenarios.
I'm a little skeptical of torture tests, and this one actually impressed me. For a rough equivalent of over 400,000 consumer miles, I was very shocked at the condition of the engine, being cleaner than I expected it to be. Gotta give props to the engineering team at Ford for that one.
