Yes, that should be very interesting and I anxiously await the results. I've done the same measurements, hot and cold, on my 93,000 mile Caribbean. It would be helpful when interpreting the data to know if the engine is a "late" 56 with the running changes to the cam plate and spacer and the somewhat earlier changes to the rocker shafts. My readings (cold/hot) at the oil pressure gauge sender were 45/38 and at the filter inlet 17/14. To my knowledge the engine has never had any significant engine work and oil pump is the Packard pump, what I call the 3rd or last generation. I've pulled a sampling of main and rod bearings and they appear in fine condition.
