I also showed him how to drill the oil passages. It is actually only one long passage that hits the top of the cam and exits into the top journal Iit will exit above the journal and just under the top seal). Then a short one to connect to the top journal. This oil passage feeds the top rod and top crank journal.

Any possibility we can get sketches or pictures?

Best thing to do is to copy the pressure lube block. I had a block that was fully ported and clearanced for the 46 crank and I used a 40 base for my pressure lube sump. I just looked at where the oil passage was and tried my best to copy it.

Best to finish filling out your profile then start your own thread, rather than replying to a two year old thread.
