It was basically to exemplify that fittings and oil line have a cost, and that' cost is Oil pressure.
Back in the day the rule of thumb was one 90* bend was about the same pressure drop as 8 feet of empty tube that same size. Obviously the exact amount depends on the specific fitting type etc. and you could easily scrutinize that 6 ways to Monday but the message is the same, fittings and hose cause pressure drop so plumb with that in mind.
True! Very much on my builders mind as he went out of his way to make sure we did not have any 90 degree uncurved angles. Oddly enough, the same 925/915 combo had higher oil pressure in the previous motor then the new one. Again, most likely because we spent way more time porting the block and heads. Some of the oil entrances/exits were really quite horrible on the stock block.
