Yellow Rose thank you & I must admit that is the most unusual mod I have ever run across but I'm gonna do it! OK you drill/tap/plug off the OE 12 0'clock saddle/bearing interface & instead plumb oil thru the cap 180 from that at 6 oclock (I ain't sure how I will plumb to there but I will figure something out). I'm still in the dark on the crank drilling, (as the crank would be in the eng) do I in effect put each rod throw at 70 ATDC & drill the crank straight up (& all the way thru the journal) at 6 o'clock? Any easy tricks to figure the 70 deg position? protractor? Your time is much appreciated. RR
