I handled a 54 Desoto V-8 with the same problem. Take it out and the oil pressure would drop off dramatically. The owner brought it in and requested a new oil pump. Okay. The new pump made no difference. The car had 93,000 miles on it and perhaps 193,000 and was quiet. Probably worn out cam bearings. I think he might have also asked for new rod bearings too.
