thanks for the input guys,i know almost nothing about the engine,came from a friend of a friend who said it ran really strong except for that one issue.I likely will pull the pan off and have a quick look before i run it but doubt I will do a full teardown. I have no idea the actual psi #s unfortunately....
I understand you not wanting to do a full teardown. Some people don't want to open that can of worms. The regular Mopar/Melling high volume pump should get you where you want to be. In the old days when I would buy a tired street hemi (these things were always tired) if it didn't have enough oil pressure I would put 50w Valvoline racing oil in it. And if that didn't bring it up I would put a hi volume pump on it. That always solved the problem. These were tired motors with 50,000 miles or 10 years on them. No telling what the clearances were. Good luck.
