Any one interested in the oiling mods I did?

The Sanborn mod I have seen (as above) does not feed only #1 as far as I can tell. It appears to be a second pressure feed line for the entire right side galley...all of the mains. A -6AN will not equal 3/8"....it's a lot closer to 5/16". I also see a lot of times when the fitting itself is the restriction even if you use a big hose.

I don't see any real difference in the R3 oiling from a stock block. If it's there, I'm not sure what it is (other than the lifter bores not breaking into the lifter galley). Actually....I wonder if a 59 deg R3 block would still break into the galley; I think the raised 48 degree angle is what allows the lifter bores to stay out of the galley.
