Of my three Packards only the '50 currently runs. The oil pressure at speed is just under 40. I don't remember what the idle pressure is but there is enough pressure to keep the lifters quiet. Outside temperature doesn't seem to have any effect on the oil pressure as the engine stays in the mid-range of the temperature gauge even on the hottest Summer days.
That's about where I am now. The spec on the 356 is 50 psi at speed, but Packard makes it very clear in the service manual that they expect the pressure to drop as the engine gets some miles on it. Since my bearings are all new and the pump appears to be in very good shape, I was hoping to be up at 50. As Dell mentioned, it may be as simple as shimming the pressure spring in the pump to get there. I think the other engines call for 40 psi at speed.
