Hi All
Well I took the process of checking the Oil Pressure and Flow to the next level. First I confirmed that the distributor shaft and hence the oil pump drive makes one revolution for each revolution of the crankshaft. Then I brought the engine up to operating temperature which is 170 F with ambient air temperature of 75-80F this is with a 180F thermostat.
I shot video of the engine oil flow in the valve gallery at various RPM levels. In the photos below you can see the differences. Then I changed the oil and did a new set of videos. Which is when I noticed what I think is the problem excessive oil flow from the rocker arms. The shafts are new but the individual rockers are the originals.
It was looking at the video and stopping it and going back and forth that really clued me into what it the problem of. Take a look at the Video

Still looking for input but I think it is worth putting the engine in the truck, road test it.
