Hello, I am getting ready to take my block to the machinist and I want to upgraqde the oiling system on my block. I am changing over to the oil thru pushrod and now I want to also enlarge the oil passages. Can someone send me a detailed description with pics of what to drill and the exact process of how to do it. I also want to do my timing cover as well. If there is a link somewhere that has all this info so I can print it out and use it as an instruction sheet that would be great. Thanks in advance for the help Later Ron
