Built around a hand-picked, seasoned block, this engine undergoes precise machining processes, including square and parallel decking, align honing of the main bearing bore, and computer-controlled cylinder honing to within .0002" straightness and roundness. The cylinders are also sonic tested for thickness to ensure quality. The rotating assembly features a cast crankshaft (4.000" stroke), forged Magnum 6.123" connecting rods with 150,000 PSI bolts, and forged pistons, externally balanced front and rear.
