Blew up my 440 with automatic trans and.....

Describe what happened and how you blew it up? were you making a pass, beating on the car etc? how did it let go.

I was just driving normal. Noticed low oil pressure at idle and before I knew it it started to rap! Load. So i killed the engine and coasted to a red light, needed to get it out of the middle of the road, fires it up and 10 seconds lated it locked and stalled.
