Description

The DFC Long Block Crate Engine is a remanufactured unit for 2006-2007 GM 6.6L Duramax LBZ applications. It features an upgraded EDM oil pump shaft to prevent slipping and oil pressure loss, and is machined with Rottler equipment for tighter tolerances than OEM. DFC uses only the best cores, reinforced internals with new pistons, rings, bearings, and rods, and cylinder heads with new valves and SBI valve seats to prevent cracking. It comes with a 5-year/100,000-mile warranty and includes a complete short block, covers, oil pan, internal components, assembled cylinder heads, and a full gasket kit.
