Lost oil pressure at the end of a run yesterday. Looked down as it was dropping to 0. Shut off the engine, coasted off the track. Checked the block , no holes, over full on the oil because of the accumilator, fired it back up , no oil pressure so I loaded it up. Today pulled the dizzy thought maybe the pump shaft may have broke or stripped, perfect shape, pulled the valve covers , thought maybe a rocker or push rod broke allowing a lifter to come out, every thing good there, pulled the pan, not a spec of anything in it. I have never heard of a big block pump going bad or do they. What should I look at next? Usually holds 45-50 at a hot idle and 70-75 hot at high rev's.  
Well I guess your down to the pump or filter
