Terry: Can you tell me more? How do you know that it wasn't oiling failure? Simply because it was mounted on a dyno? Did it have a site gauge in the pan to determine if the oil was being retained in the top end? Someone posted a while back that even at 5K RPM, there was only 1/2 qt. left in the pan. I would think that high G force corners are a contributing factor, but the oiling system is certainly a problem.
I can tell you that wrecker Duratec motors are very hard to find here as they get snapped up quickly. They're going in ATX and MTX cars. Always oiling failure.
