See that Rick, should have balanced the motor and none of that would have happened!

I'm running cast crank and shift at 7k at the strip and sometimes on the street. [img]<<GRAEMLIN_URL>>/hmmm.gif[/img] Guys have running them for years and haven't had problems as long as everything is balanced.

Well....let's not go that far. I'm sure his motor was balanced. Although, looking at the dome of the piston in the picture, I'm sure he was running more than 10.4 compression. Rick will chime in and give us more details.

My point is that a lot of motors have been run hard on a good GM cast iron crank without issues.
