360 oil psi dropped all the sudden

Op, did you build your engine yourself or did you buy it? I'm wondering about your bearing clearance. I've run my duster for years with a stock pan with no issues. I've even had numerous people tell me the car pulls the driver side wheel off the ground. I've never had an issue with oil pressure. With the clearance being not right you pressure may be ok till the oil thins when warm. Now that you have metal in the oil it sounds like your be pulling it apart. Keep us posted.
