Oil Filter Leaking at First Prime of Oil Pump

Every time I start the 360 oil pours all over the ground, replaced filter, replaced gasket under block plate with sealant, no 45 degree adapter, no paint on anything. This time a cured it up instead of pouring all over the exhaust it simply blew all over my front passenger wheel. Can not keep oil in this thing. It is a 79 360 out of a truck. Of course replaced pan to a car pan, new oil pick up and gaskets there also. Car sounds amazing but can’t move forward to time it properly because oil just simply will not stay in the darn thing. Super frustrated here, ready to run it till she blows!!!! HELP
