Been reading through this thread, here comes a couple newbie questions... so I understand the concensus is sloppy build in that the crank wasn't thoroughly checked... so I assume this means some machining of the crank should have taken place but didn't? Second, a comment was made about strokers beating up pistons... any particular reason why a stroker would be more damaging to pistons than a stock stroke? Or are they not? Again, forgive me if my questions seem ignorant, but I figure the best way to learn is to ask...

The block should have been machined to make sure the crank journals are perfectly straight and the crank should have been checked for runout and straightness. Strokers are generally harder on pistons because of the angle of the connecting rod at the bottom of the stroke is more extreme than usual and causes "piston rock"

Duh... I knew that about strokers too... thanks for reminding me though! And that's what I thought had occured with your block/crank, just wanted to double check my understanding... Live a little, learn a lot right...

Definitely, thanks for the info though. I'm still learning, have lots left to learn and freely admit it... Half the fun is learning though, In my opinion. Best of luck to you with the rebuild!
