Any one interested in the oiling mods I did?

I am confident the addition of the cam bearing feeds and rocker feeds would make no difference in the 'does #4 fail to get oil because the oil won't make the turn' discussion. I can't think of any reason they would. My diagram, again, is aimed at that question alone. It's not intended to be a cover-all for the SBM oil system.

Gregcon just so we are clear, we are only saying that the oil has trouble turning to #4 main with a stock oiling system with a high volume pump. No one is saying that it is still a problem after you modify the system. The drawing you made should not have any trouble because the issues that would cause the velocity issue have been removed. As I posted before I have failed main bearings 2&4 even though there was plenty of volume going too them because there was not enough of a restriction in the passages feeding the rockers. Because there was no restriction, there was inadequate pressure at those two main bearings. Surely that will convince you that pressure does not fix everything.
