Any one interested in the oiling mods I did?
Here is the main cap...I enlarged the oil feed hole from .470" to .531 (17/32). I used a 17/32" reamer to enlarge all of the oil pressure passages from the pump to the galley. I figured 17/32" is 11% bigger than 1/2" so it's like going to 11 lol. This particular cap allowed me to go to 17/32" without getting too close to the edge of the cap. In the first posts made by Guitar Jones, you can see his passage was getting close to the edge (too close IMO). I also offset milled the cap hole to make it align with the block hole, now they align very closely. The tough part about this is you really want to round over the edges of the holes for a smoother transition, but you can't because every bit you remove eats away at the sealing surface.
