That's right. To date, I've never seen a factory Chrysler rod just "break" without outside influence. Not one. I think you'd be hard pressed to find proof of it. It's almost always "something else" that causes it.
Don't underestimate the power of bling :)
Cylinder heads seem to be another place where this sort of BS goes on..
"By the time we service your factory heads, you may as well get Alloy ones"... That's just not the case in most stock-ish situations.
