Crank breakers wanted

My Dad killed a couple Callies cranks during his dirt track days, but all of them were due to a rod or main journal being set too tight and killing the crank. He had a rod journal so tight one night it warped the crank. He raced out of his own pocket, so most of the time the cheaper fix was the right fix to race the next week. He had a local shop try to straighten the crank, but they wound up weakening it. The following week, it wound up braking right in that spot and killed the engine.
