We now offer our reproduction cast iron High Pressure oil pump assembly, made directly from original OEM specs. For engines which have factory 4 quart capacity oil pans, we have found that the high volume pump can sometimes suck the pan dry, resulting in bearing damage. For those factory capacity (non deep sump) engines, the high pressure pump is a great alternative. You still get the added benefit of oil which is being pumped at a higher pressure, without the added volume which can suck the smaller capacity pans dry. Completely brand new, assembled and ready to install. Don't forget gaskets and attaching bolts as well (listed separately.)
