oil pump

Get a Melling M72HV pump. Take it apart and drill the feed passage to 1/2 inch. Also the main cap passage. If yo have a right angle filter adapter drill that. Or if you have a straight screw on type take the plate off and drill the holes bigger and add more holes between the holes that are there. Also only use a NAPA gold or Wicks filters all others are junk ,they do not flow. I did this on my motor and my pressure is pegged when cold and I didn't add a pressure spring. 40 - 50 hot at idle. I am also running a remote filter and Cooler. Your oil system is what keeps it together Don't get lazy here , you can do it all yourself. Safety wire all of the pump bolts when reassembled. Steve
