RE: 4.6 overheated???
knocking sound is probably detonation, caused by the overheating. how did you overheat it, were you just driving around or racing? im guessing you already run 93 octane with a supercharger. this could be a serious problem if it continues, but it could have been temporary due to the overheated condition. hopefully no real damage occured.

Hmmm, overheating wouldn't really cause something in the crank to come apart. If the something in the rotating assembly is indeed the problem, it probably happened while you were running the engine hard and then it overheated. I had a friend who spun a bearing while trying to go fast.

Wait, let me get this straight...you did a 5 minute constant burnout at 6500rpm? Dude the redline is at 5700, you probably damaged the internals being that you were probably bouncing off the revlimiter.
