The DFC Street Series Engines are part of DFC’s Flagship product line and are a great choice for the daily driver, work truck owner, and diesel enthusiast that wants a quality rebuild engine. DFC remanufactures each engine to meet stringent guidelines. While rebuilding the engine, DFC makes crucial improvements to help your engine maintain durability and reliability, even with added horsepower. Each engine is machined using Rottler equipment. These precision machines ensure your engine is built to tolerances that are tighter than OEM specifications for a more efficient and longer-lasting engine!

Engine Remanufacturing

During the build, DFC addresses common leak areas such as an added bead of silicone on the main cap plate to eliminate the potential for leaks down the road. DFC engines are matched with near-identical weight piston and connecting rod assemblies. As a result, you get a smoother running engine that feels more balanced with less noise. This remanufactured Long Block includes new pistons, rings, bearings, and seals.

Cylinder Head

Unlike some others in the industry that re-use wear items like valve guides, DFC replaces each one with new cast guides in every cylinder head. They don’t stop there; instead of just re-grinding high mileage valves, DFC installs all new valves from high-quality sources like MAHLE or SBI. To address common cracking areas in the cylinder head, DFC 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.

ARP Fasteners

DFC Street Series engines come standard with ARP 2000 Series Head Studs to give you peace of mind that your new engine won’t have head gasket issues like a factory Ford engine. Not only does DFC use ARP Head Studs to ensure the heads don’t lift off the block, they also replace the factory connecting rod bolts with ARP Fasteners when assembling the bottom end of your 6.0L Powerstroke engine to ensure that you have an engine that is more dependable than the original.


DFC engines are remanufactured by diesel enthusiasts for diesel enthusiasts. DFC offers one of the most comprehensive warranties in the industry. Each DFC Street Series Long Block Engine comes standard with a 5-year, 100,000 mile warranty.

Street Series 6.0L Long Block Includes:

Complete short block with front cover and seal, rear cover with main seal, oil pan, cylinder heads, all rockers and pushrods installed, ARP series 2000 head studs, ARP connecting rod bolts, and a complete top end gasket kit to finish the installation.
