The DFC Diesel Remanufactured Street Series Long Block Crate Engine is a cost effective replacement to a factory engine replacement in your 2011-2019 Ford 6.7L Powerstroke. Built for the daily driver, work truck owner, and diesel enthusiast that wants a high quality build, the Street Series Long Block is constructed to meet the most strict guidelines. DFC makes crucial improvements that help your engine maintain its performance ability without reducing reliability. Remanufactured using advanced Rottler maching equipment, you can be sure your engine is built to tolerances that are more precise than the factory specs for an efficient and long lasting engine!


Engine Remanufacturing

DFC engines are usually matched with near identical weight piston and connecting rod assemblies. As a result, you get a smoother running engine that creates less noise and feels more balanced. This remanufactured Long Block includes new pistons, rings, bearings, and seals.


Cylinder Head

Each 6.7L Powerstroke Street Series engine comes standard with O-ringed cylinder heads. DFC replaces each valve guide with a new cast guide in every cylinder head. Instead of just giving old valves a re-grind, DFC installs all new valves from high quality sources like MAHLE or SBI. 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.



DFC engines are remanufactured by diesel enthusiasts and are built for diesel enthusiasts. To show their pride, 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.

Complete long block with cylinder heads, all rockers and pushrods installed, valve covers, complete top end gasket kit to finish installation.
