Original 3.4 L, Crankshaft, Connecting Rods and 8 to 1 Pistons 40 over. It is believed that the crankshaft bearing surfaces measured at standard. Bearing surfaces are fair condition. The bearing surfaces would need reconditioned before use. Connecting rods are original to the engine. The pistons are from the original engine rebuilt in the late 80s. These parts came from a 1954 Jaguar XK120 SE 3.4L. The engine was running at the time of removal of the parts. The reason for removal of the parts is I built the engine to performance standards with all new components.
