We start with a vintage era original Oldsmobile engine block that has been sonic checked, baked blasted and shot peened. We then install our brass core plugs and oil galley plugs. Each block receives our ultra high strength ARP main fasteners, a line hone, cylinder bore hone with deck plates and a deck surfacing. This process allows the cylinder head deck surface to be in perfect alignment with the main housing bore. The short block is then fitted with a super strong high performance nodular iron crankshaft that has been shot peened, chamfered, balanced and blue printed. The short block then gets fitted with forged aluminum pistons and an upgraded wrist pin. Each piston is hung onto our shot peened and weight balanced y connecting rods that are outfitted with ARP fasteners. Every engine from Olds Performance Products receives the oil restrictor kit, main bearings, rod bearings and our camshaft bearings. This short block comes fully assembled, balanced, blue printed and ready for ship. Short block only.  Please contact prior to order placement.
