I had my 360 Dodge rebuilt (stock) by a local machine shop (now defunct) 5 years ago. It sat in the FF frame sealed up while I completed the truck around it. The machine shop instaled what I assumed to be some form of break in oil. I primed the pump with a drill down through the distributor hole and got 50 Pounds of pressure as well as plenty of flow around the lifters. Installed new MSD electronics hit the key and fired up and ran immediatly with 50 pounds at idle. After idling for 3 minutes the pressure dropped to about 10 pounds and looked like it was falling more. Bummer !!!! I am inclined to think that the relief valve in the pump is stuck open. Would appreciate some advice before I tear it down
