This is a brand new engine. New STD bore block, crank, Carrillo Rods, CP pistons, ATI Super dampner, valves, springs, Ti retainers,  engine bearings, valve cover, all sensors and plastics are new.. The oil pan has extra baffeling in it as well and has a  Teflon coated windage tray. The only resude parts are cams, intake manifold and the cylinder head.  Which was redone my Endyn many years ago.
