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:
DFC engines are built utilizing some of the most advanced machining equipment in North America. This Rottler equipment helps ensure the engines feature tolerances that are better than OEM specifications. The DFC long 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 long blocks include reinforced internals with new pistons, rings, valves, springs, doweled oil pump, bearings, and rods.
Cylinder Head:
Unlike some 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.
Street Series 6.6L Long Block Includes:
Complete long block with the front cover and seal, rear cover with main seal, oil pan, all new internal components, cylinder heads with all rockers and pushrods installed, doweled oil pump gear, woodruff keyed cam shaft and complete gasket kit for installation.
ISO Certified:
This engine is manufactured in an ISO 9001:2015 Certified Quality Management System facility to meet strict international quality standards, ensuring that every engine is built for reliability and long service life.

New Engine Checklist & Things You Need To Know:
- New Oil Cooler - Required For Warranty (Sold Separately)
- New Filters - Air, Oil, Fuel - Required For Warranty (Sold Separately)
- New Water Pump - Required For Warranty (Sold Separately)
- New Lubricating Oil - Required For Warranty (Sold Separately)
- Injectors - highly recommended especially on higher model engines or engines with contaminated fuel.
- Turbocharger - recommended if mileage over 125K, mandatory if shaft play, or if engine was dusted.
- Evans Waterless Coolant - recommended upgrade to prevent corrosion and boilover.
- Long Block engines typically consist of a short block with cylinder heads and are ready for the final buildup.
- This long block does not include bolt-on components such as the valve covers, intake, exhaust, fuel system, or turbo components.
- The parts above must be swapped over from your existing engine and then installed on your new DFC Long Block.
- Engine Warranty Is Void If Not Installed With The Correct Fluids as Specified By The Manufacturer.
- The specific brand of each component may change due to part availability at the time of each build.
- Parts are chosen at the discretion of DFC and cannot be specially requested.
- DFC uses only the best components sourced from multiple brands during the remanufacturing process.
