Yes this is the engine that makes that horsepower. I did rebuild it in the past but still left it at standard bore as there was not much wear through the engine. I am taking the cylinders out 20 thou now. It didn't have excessive lifter bore wear and I had the machine Shop measure them and check them and they were still standard size. All gallery plugs are in place and triple checked. The main bearing clearances where 1 to 1.5 thou with the rear one being at 2 thou. I spent 2 years chasing the oil pressure problem on several forums trying different thingstand eventually gave up in frustration. I am going to speak to a Mopar performance shop this week about boiling modifications and I'll mention the ones you suggested. Thanks
