Thanks again Gene and Chipper. So about 10 lbs of oil pressure at 50 mph is ok? Perhaps there is more clearance somewhere than there should be, but the engine was very tight when first rebuilt (had to tow it to initially get the engine to turn over--starter wouldn't do it)

Oil pressure is an indication that the pump is working. These engines were designed for low pressure oiling systems. Modern engines use the crankcase oil to help cool the engines. That requires much higher flow rates than just lubricating the moving parts.

The 10 pounds at 50 MPH sounds very typical for a 1936. The only thing "loose" that would cause a pressure loss would be the main bearins as they are the only thing that get full oil pressure.
