Hi. I made a shaft of proper dimensions and ran it with a drill. Wow did that make a difference. Oil pressure poped right up to 60 PSI and stayed steady. I was worried that I may have had something left out or routed wrong cause I added a remote filter and cooler and completely blocked off the original filter area.I brought the oil ins and outs directly from the oil pump galley and back into the block main galley. Hopefully I wont have much pressure drop. Any ideas as to what to expect in that regard??
