Factory Fitment With Upgraded Internal Precision

The Street Series Long Block from DFC is designed as a factory-fit solution that improves on every critical weak spot in the 6.0L Powerstroke platform. This engine starts with a remanufactured block that’s bored for oversized pistons and machined using advanced Rottler equipment for pinpoint accuracy. It’s assembled using all new internal components including pistons, rings, bearings, gaskets, and seals that meet or exceed OEM specifications. The cylinder heads are also remanufactured and upgraded with new valves, springs, hardened seats, stem seals, and cast guides, while being magnafluxed and resurfaced for optimal sealing. ARP Series 2000 or OptiTorque head studs and ARP connecting rod bolts are standard, reinforcing the engine for better durability under load. DFC also incorporates improved gasket sealing methods in areas known to leak on the original 6.0L, helping to eliminate long-term maintenance headaches. Every long block includes a full top-end gasket kit and comes pre-assembled with rockers and pushrods to simplify installation. Built with attention to detail and backed by a serious warranty, this engine delivers a reliable, high-quality replacement without the complexity of heavy performance builds.
