Then my junk low powered 7500+ rpm motor must be the exception or maybe I got a good one.



I must have been exception 2 and 3 as I had them on two engines (440 that I constantly spun to 7100 RPM and the bearings always looked like new. After 15 years is still running in my buddies Satellite. Same with the 496 that I ran for a few years and sold to another buddy).
