My second poly V8 is now complete. I do not consider myself a master engine builder, but I do know now most of the pitfalls of these old engines. My oil pressure problem was a missing plug. There is a false plug on the rear of these engines on the driver's side. Behind it, there is another plug that caps off the oil galley. With that plug installed, I got an instant 65 lbs. of oil pressure at 200 rpm with a drill motor. It's amazing how little oil pressure you get with a 3/8 in hole in the oil circuit. As soon as the new wires get here will give a test fire. More to come.
