"The world record"? Who was the competition?
You may believe what you wish, and you may do with your engines what you wish. The fact remains, no manufacturer lets the engines run or drives the new cars around for the equivalent of several hundred miles. Engines are built to better tolerances, but they are not run in when you get them.
