171,000 mi. on 96 4L. Oil pressure drop too 0 after 4 or 5 mi. of running
at 60mph then stopping. I just replaced the oil pump and still have the
same problem, only worse now. It is an aftermarket pump, could I have just
installed a bad pump?

Oil pressure depends on pump quality and bearing clearance both. If you put
a new pump on an engine with bad bearings, then you didn't help yourself
much. Did you check the accuracy of the oil gauge before installing the new
pump? Isolated oil pump failures are rare, because the pump is the best
lubricated part of the engine. They do happen, of course, but they are
rare.

Thank you Earle. I was thinking that was the problem but, I was in denial
and hopping for another answer.

Verify the oil pressure with a Real gauge, like all Hot Rodders use
aftermarket sets by Stewart Warner: http://www.stewartwarner.com/ or
