I think we got a little off track here. Something about a 360 throwing a rod and then building a workable 318. When you build a motor (any motor), you need a plan. without going into a plan book here, I just want to put my two cents on the above mention 318. I would not install a High Volume oil pump with a stock pan. You can run the pump dry and throw a rod. Sounds liken he is on the way of doing the same again.
