An Affordable Path Back To A Dependable 6.0L

A blown 6.0L Powerstroke doesn't have to mean an expensive engine replacement or a risky gamble on a used unit. The DFC Diesel KORE Series Long Block was built specifically to bridge that gap, giving 2004 Super Duty and Excursion owners a quality remanufactured engine at a more accessible price point. DFC keeps costs down by leaving out components that are commonly reused or easily sourced separately, without cutting any corners on the actual remanufacturing process itself. Every long block is machined using Rottler equipment, some of the most advanced machining technology in North America, resulting in tolerances that exceed original OEM specifications. Inside, you're getting all new pistons, rings, bearings, gaskets, seals, valves, springs, hardened seats, stem seals, and cast guides, along with upgraded rod bolts and Total Seal gapless piston rings, with head studs included depending on availability. DFC also builds in improved gasket sealing methods specifically targeting the common leak points this platform is known for. Whether you're keeping a work truck running or restoring a reliable daily driver, this long block gives you real remanufactured quality without paying for a full engine package.

Precision Machining With Purposeful Upgrades To Known Weak Points

The DFC Diesel KORE602004STAULB is a remanufactured long block engineered specifically for 2004 Ford F250 and F350 Super Duty trucks equipped with the 6.0L Powerstroke engine featuring 18mm cylinder head dowel pins, and 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, along with upgraded rod bolts and Total Seal gapless piston rings, with head studs included depending on availability. This engine is built for models with the ICP sensor located in the front passenger valve cover, an important distinction specific to this 2004 production run. The long block ships as a complete short block assembly with the cylinder heads included, along with a complete top end gasket kit and silicone to finish the installation. It's worth noting this long block does not include the front cover, rear cover, oil pump, upper oil pan mounting plate, oil pan, or oil pickup tube. Every engine is manufactured in an ISO 9001:2015 certified facility and backed by a 1 year, unlimited mileage manufacturer warranty.
