It's been a while since I posted but I figured out the oil pressure issue...and it was strange. We pulled the oil pan at the local repair shop and everything looked okay, we found a little crud in the bottom of the pan. When we removed the intake the lifter and the pushrod were lying in the valley! We replaced the lifter and put it back together and she seems to be running well. Oil pressure is good, while it was apart we checked some of the bearings and they looked okay, no damage.

She just got back from a three day trip to the tire store because they didn't have and couldn't get left handed lug nuts. We ended up getting regular nuts from NAPA and I'm going to get the fancy acorn style and replace them later. The new tires and wheels sure look sharp though. I'm really happy to finally have a functional hot rod (until I break it again).
