When I freshened my motor last spring (355 LT1, running 16psig boost) I 
decided to replace all of the rods with fresh ones. After all, they were 
the stock rods, had 60k miles on them, and though they looked good, it 
seemed like a cheap thing to do to insure trouble free operation. So a 
fresh set of GMPP rods went on.

4000 miles later one of the rods separated and sent shrapnel through the 
rest of the motor. A 1" section of the rod just disintegrated. The rod 
wasn't twisted, no other signs of problems, it didn't even spin the 
bearing. The motor kept running, and if a piece of metal hadn't gone 
through the side of the oil pan, there wouldn't even have been a leak.

That almost made me give up on this sport :-)
