Oil passing from the cam as well as residual oil draining from the heads as well as oil passing from the rod to rod side clearence will be more than enough lube the cylinders and wrist pins. I agree with Darren's thoughts of gaining HP running a tight scraper and cleaning the excessive oil from the rotationg assembly as it passes through the heavy concentration of oil(bottom half of rotation) where it has more chance of picking up more oil that is returning to the pan as well as drawing from the sump,even with a tray the oil gathers heavely on it before passing to the sump.
