'84 GT350 - new engine loses oil pressure after warming up - Ford Forums

What can be wrong? When the brand new engine in my '84 GT 350 reaches operating temp, the oil pressure drops drastically (according to the gauge). It will even reach zero when idling. Then the car is very difficult to restart after the engine is warm. Almost as if the battery is dying. If I let it sit a while and cool off, it starts fine and the oil pressure returns, only to begin the cycle all over again. I'm at a loss. Any ideas???

sounds like timing is off and also your new motor sounds like it has a bearing problem

I agree with garneym, timing sounds to be advanced too much & possibily excessive clearance at the bearings.
