A Stronger Foundation For A Known Weak Point

The 6.4L Powerstroke has a well-earned reputation for head gasket trouble, and a proper rebuild needs to address that weak point head on. The DFC Diesel KORE Series Long Block gives 2008-2010 Super Duty owners a remanufactured engine built specifically to correct that known failure area. Every long block features O-ringed cylinder heads, a purposeful upgrade designed to improve head gasket sealing under the kind of boost and cylinder pressure this engine sees in real use. DFC machines each long block using Rottler equipment, delivering tolerances tighter than OEM specifications, and builds in upgraded connecting rod bolts along with Total Seal gapless piston rings for a more durable, better sealed engine overall. Because this is a serious rebuild rather than a quick patch job, DFC also requires a few supporting components at the time of install, including a new oil cooler, new air, oil, and fuel filters, a new water pump, and new lubricating oil, all necessary to keep the warranty valid. Whether you're addressing a failed head gasket for good or replacing a tired 6.4L before it lets you down, this long block gives you a rebuild built around this engine's actual weak points.

Precision Machining With Purposeful Upgrades To Known Weak Points

The DFC Diesel KORE640810STAULB is a remanufactured long block engineered specifically for 2008-2010 Ford F250 and F350 Super Duty trucks equipped with the 6.4L Powerstroke engine, compatible with both automatic and manual transmission applications. Every long block is machined using Rottler equipment, delivering tolerances that exceed OEM specifications throughout the build. The engine includes all new pistons, rings, bearings, gaskets, seals, valves, springs, hardened seats, stem seals, and cast guides, and comes standard with O-ringed cylinder heads and upgraded connecting rod bolts, both addressing common failure points on this platform. It ships as a complete short block assembly with the cylinder heads included, along with a complete top end gasket kit to finish the installation. It's worth noting this long block does not include the front cover, rear cover, oil pump, upper or lower oil pan, oil pickup tube, rocker arms, pushrods, or valve bridges, and that top end gaskets beyond what's included, the injector return line seal kit, and the turbocharger gasket kit are not included and must be sourced separately. To maintain warranty coverage, a new oil cooler, new air, oil, and fuel filters, a new water pump, and new lubricating oil are required at the time of installation. Every engine is manufactured in an ISO 9001:2015 certified facility and backed by a 1 year, unlimited mileage manufacturer warranty.
