My new 427 blew at the track Friday night. The bottom of the oil pan is dented and it has a 2" hole in the pan on the passenger side at the front of the motor. I had a 5 trips to the track on it before friday. I have not touched it yet to see what happened. I will post some pics as I do the autopsy. I just hope the damage is limited to the bottom end so I can reuse as much as possible on the next motor.
