I just built a 408, '95 magnum block, 555 hydralic roller, ported r/t magnum heads, hv oil pump, stock pan. The engine had about 2 -3 hr run time and I changed the breakin oil, I cut the oil filter open and found bearing matirial. I tore down the engine and #2 main bearing was down to the brass. the oil pressure was 60 at cold idle 30 hot, over 65 hot at 6000 rpm. I would like to look at an oil schematic befor reasembly. Also listen to any ideas as the cause of the problem.
