Product Description
Blessed Performance can replace the blown engine in your 2007.5-2010 GM 6.6L Duramax LMM with a high-quality DFC Remanufactured Street Series Long Block Engine. By being committed to their high standards, DFC makes crucial improvements during the remanufacturing process to maintain reliability even in applications that have additional horsepower. DFC focuses on upgrading the Duramax weaknesses from the factory by installing such items as an EDM oil pump shaft with a hardened dowel to prevent slipping and the risk of an oil pressure loss. DFC uses Rottler machining equipment that allows for tolerances tighter than OEM specifications. DFC checks every core before the build process and chooses the best cores while rejecting any components that require considerable “restoring” to maintain the highest standards possible.
Engine Remanufacturing
The DFC short block is machined with near identical weight piston and connecting rod assemblies to help you get a smoother running engine that makes less noise and is more balanced. DFC short blocks include reinforced internals with new pistons, rings, doweled oil pump, bearings, and rods.
Cylinder Head
Unlike other engine builders in the industry that re-use wearing items like valves and valves guides, DFC installs all new valves from high quality sources like MAHLE or SBI and replaces each valve guide with a new cast guide in every cylinder head. To address common cracking areas in the cylinder head, DFC also machines each head to remove the factory hardened seat material. DFC then installs new SBI valve seats to help eliminate premature cracking, giving you a more durable cylinder head.
Warranty
DFC engines are remanufactured by diesel enthusiasts for diesel enthusiasts. DFC stands behind their products with one of the industry’s leading 5 year 100,000 mile warranty.
