HV Oil Pump/rear cap bolt clearance?

Even then, I still have to do a little "custom fitting" of the oil pan. The high volume pump will hit the side & bottom of the pan also. Test fit it without a gasket and get it to seat on the block surface. Keep trying, then banging with a ball peen hammer, then test fit, then bang a little more, etc. Repeat until oil pan will fit on the block flat without the gasket, then it will be fine with the gasket. #-o


With just a little bit of banging, you can get it to fit. :violent1:
Me too, I had to form the rear of the 7 qt. Milodon wide bottom pan, a bunch to clear the Melling HV. Ball peen works fine.
With the baffles in the pan I thought the stock windage tray would keep the oil up and not let it drain, so out it went to EBAY. A diamond expanded steel tray would be the better than stock tray. But 6500 rpm peak is not a race motor.
