Default 92 Ford f150 5.0 302 rough idle and squealing even when serpintine belts off

My truck just started squealing a very high pitch sound from engine. It has a new serpentine belt and pulleys are good. Here's were it gets crazy....took belt and ran the motor and still it squeals...it also dies while in idle...does anyone know whats going on?

Without a belt, the only things moving are the cam, crank, and the distributor. Can you tell if it's coming from the front or the back of the engine? Have you changed the oil since this has started happening? Notice any bearing material in the old oil?
