When mine broke on the LT1 cheby I had. It took out the crank and radiator too. The crank broke in front of #2 crank bearing. The pulley went through part of a 4 core radiator. It was explained to me by the guy who balanced and built my LT1. That when you change the dampener to a lightweight dampener. You change the harmonics in the crank. I had changed to the lightweight after I had installed the motor. So it was not balanced with everything else.

Here's some pic's I pulled.

Nope it didn't even hit the crankcase. I think it snap jumped up from tension or just rotated out and plopped onto the undertray. I thought it was track rubber coming off the tires...until I noticed my brake light, battery light, and no charge going into the batt. No PS is a bitch on 285 R1'S
