Approx 2500 hrs, in great shape. New head gasket and head bolts (genuine VP). Fresh coolant, oil and filter change. Engine has about 4 hrs on it after head gasket change. Supercharger works great. Compression test done, 340 - 370 psi. Injectors were also tested. I have videos of the engine running at various speed and loads. Leak was at #6 cylinder, oil from pressure port to top end was leaking externally. No fluid migration. This is an awesome engine with thousands of hrs left. Made 245 HP (3600rpm) and 415 ftlb (2000rpm) on the dyno. Includes intermediate assembly, exhaust elbow, down pipe, wiring harness, gauges and some spare parts. This engine provides excellent performance with a very reliable engine design. Replace your gas engine to improve fuel economy, reliability and resale value. $9800 OBO.
