loosing oil pressire on hard accel and at idle

Did you actually measure the crank journals with a mic? Aluminum rods take different clearances and bearings because of the rate of expansion and the alignment dowels. Source parts are great at being good. Not good at being great, and alimunim needs great. I would look at the oil pickup to pan clearance as far as the accel goes, and the pressure at idle isnt bad depending on the oil. What does ti do at 200rpm? 3500?
