A long time ago, I had a master mechanic tell me that he could always tell an engine that was lugged when he tore it down, the tops of the rod bearings would always be worn out. He said that there should be no way the rods would wear that way unless the engine was lugged.
I went to Automotive school for a year when I was a kid. My instructor said the definition of lugging is: "Anytime you open the throttle and the RPM's don't increase, you are lugging"
I've never had a car with a rev limiter before the S, I sure get a lot of use out of it now. Don't think I will have any issues with the tops of my rod bearings wearing out.
