Re: 360 Oil Pressure Question

[Mike Shaw <bandsoperations@xxxxxxxxx>]

Hi Dennis:
I had a 2001 dodge with 100,000 miles never had that
low pressure. 30 at 700rpm and about 50 at 1500 rpm.
sounds like to much clearence or one of the oil plugs
was left out. There are two if I remember right. One
goes in the back and inside of the block the other in
under the oil filter plate. Someone else my have a
better ideal.
