Eagle FE cranks have a high failure rate.
At the risk of seeming needy (I'm not), there are other places to buy parts than Summit or Jegs. Where do you think engine builders buy their parts from? I can most likely beat anyone's pricing on anything and have actually had my hands on a few FE's......call Jegs up and ask the guy that answers the phone how many FE's he's built.
Again, feel free to email me or call me.
