I'm not arguing. I'm hoping to save someone grief. Oil loss at the crank is controlled by bearing clearance. Not Rod side clearance or anything else.
The rockers, even with a groove in the cam only require the oil that leaks past the sides, and just like the crank only leaks what the clearance between the rocker and the shaft.
The only other oil leak is when the rocker is on the seat and oil goes to the adjuster.
You can move the oil hole in the main bearing anywhere you want it. The rods must get full pressure, full flow when the piston is ~70 degrees ATDC. It's common engineering. Chrysler and ford fudged it for packaging reasons.
You can do anything you want, but if you want to make power a over 8k you have to fix the oil timing.
Look at how Chevy did it. That's how it should be. Chrysler got it wrong.
