Any one interested in the oiling mods I did?

In this description are you referring to the stock oiling or the modified. In the stock system, because the oil continues its flow from number 1 main over to the drivers side, you might as well say it is not blocked at the end of the galley.
My interest is purely academic as well and I have read your excellent link about oiling and that article also says that branch circuits contribute to uneven feed to some bearings.
Ironically you have used the word turbulence which is the word that Sanborn use to use to describe the problem as well. Perhaps that is a more accurate description.

Interesting. True that the feed for the drivers side lifters comes off the number 1 main, that main only feeds one rod. I still think it should be blocked or at the least very restricted, but you can only block it if you are using solid lifters.

I alway have issues getting my head around turbulence. I can’t imagine how low the velocity of the fluid moving through a tube has to be to get laminar flow, or if that’s even possible to achieve. I’m sure viscosity, surface finish, area and who knows what else changes when turbulence is high enough to stop the fluid from making a 90 degree turn.

One nice thing is that now, with modern oils and their ability to lubricate at very light grades has to help as far as pumping and getting through the spider web of galleries is concerned. I have my pan off and I may just suck it up and add a second pick up. I probably don’t need it, but I went back and read a couple of the books I have, and it made me remember that (this was tested by...Bob Tarozzi IIRC) that just adding a HV pump and NOT increasing the inlet diameter makes the HV pump only produce like a standard volume pump.

Or, I could throw a standard volume pump on there...but that makes me nervous.
