340-904 thrust bearing/crank issue

Once again thank you all for the advice. I'll wait for the findings of the machine shop and proceed with the rebuild/repair of the 340 from there. It's hard to believe, but the thing actually ran pretty good even with the damage. I was checking the timing when I noticed the balancer moving back and forth. I'm thinking things could have ended up much worse. This site is terriffic and I'll be spending alot of what little free time I have consulting with all of you!:thumrigh:
