Thanks Coop. I was just working on this yesterday. I dropped the pan (easier said than done!) and installed a high volume Melling pump. I tested it by spinning the pump with a drill and got higher pressures than with the old one so that might have fixed it.

Today I will get it all back together and fire it up to really test it. My fingers are crossed big time on this. Hoping to move forward rather than have to tear the engine back out!!!

The block had new cam bearings installed at the machine shop. I know I have all the oil galley plugs in and the bearing clearances were all good so that really only leaves the pump. (I think)
