Jerry: I think I see what your saying , but that 216 oil circuit is far from a closed loop. It is by nature 2 main branches and the oil pressure gauge only does a moderate job of showing psi in one branch of the circuit.
In the 1950's garages sold a little plunger-like tool to ram pressure up the 216 oil tube to the head to try and unclog dirt and sludge from that line.That engine plaque is what aided in starving those rockers. Wouldn't increasing oil pump volume just cause more blowby elsewhere if the clog would not come loose?
That stock pump on a stock 216 is well balanced to provide just right flow to vital parts. It's not low pressure as it reads on the gauge, its just right.
Are you saying that if the main bearings and cam bearings are worn so much that the oil psi reading is low, then a higher capacity pump will cure that wear?
Will that hi-capacity pump need a different oil distribution valve and setting?
What effect will the increase in capacity have on the flow from the target nozzles in the oil pan?
