Built for drivers who demand consistent performance under pressure, this engine is rated up to 600 horsepower at the flywheel, giving you the confidence to tow, haul, or climb without second-guessing what’s under the hood. It comes equipped with critical enhancements like a Stage 2 billet camshaft and Total Seal gapless piston rings, both designed to deliver power with reliability in mind. This long block is built to handle the real-world abuse that comes with loaded trailers, steep inclines, and long miles on the highway. You’ll also get ceramic-coated piston crowns and dry film-coated skirts for added heat resistance and durability under load. DFC doesn't just assemble engines, they engineer them to handle everything from jobsite demands to weekend trailering. Whether you’re running a 2004 F250 or F350 with a 6.0L Powerstroke, this long block delivers the kind of strength that makes hard work feel a lot easier.\u003c\/p\u003e\n\u003ch4\u003eEvery Piece Designed With Serious Work In Mind\u003c\/h4\u003e\n\u003cp\u003eUnder the hood, this Tow\/Haul Series long block packs the kind of components serious builders look for. Starting with the DFC long block assembly, it’s built from the ground up with ARP connecting rod bolts and either ARP 2000 or OptiTorque head studs, depending on availability. These fasteners help maintain head and rod integrity under extreme cylinder pressure, which is essential when pushing the upper limits of power and load. The engine also features O-ringed cylinder heads to improve sealing under boost, a key feature when towing or running upgraded turbos. Internally, the pistons have chamfered bowls and are treated with ceramic coating on the crowns, along with dry film coating on the skirts to reduce friction and improve heat dissipation. Heavy-duty Manton pushrods and a Stage 2 billet camshaft round out the valvetrain, boosting reliability and top-end stability. You’ll also receive a full top-end gasket kit, rockers, and pushrods pre-installed, making the install process smoother and faster. Built for 2004 model year Ford F250 and F350 trucks with the 6.0L Powerstroke, this engine delivers the performance and toughness that heavy-duty work demands.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e Fits: \u003c\/strong\u003e 2004 Ford F250\/F350 6.0L Powerstroke\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eRated for up to 600 HP at the flywheel\u003c\/li\u003e\n\u003cli\u003eDesigned specifically for towing and hauling use\u003c\/li\u003e\n\u003cli\u003eIncludes all Street Series upgrades plus added enhancements\u003c\/li\u003e\n\u003cli\u003eBuilt to support performance applications up to 550 HP\u003c\/li\u003e\n\u003cli\u003eCompatible with 2004 Ford F250 and F350 6.0L Powerstroke\u003c\/li\u003e\n\u003cli\u003eLong block includes short block, cylinder heads, and gasket kit\u003c\/li\u003e\n\u003cli\u003eHead studs may be ARP 2000 or OptiTorque based on availability\u003c\/li\u003e\n\u003cli\u003eEngine includes pre-installed rockers and pushrods\u003c\/li\u003e\n\u003cli\u003eIdeal for customers upgrading from stock or replacing worn engines\u003c\/li\u003e\n\u003cli\u003eProfessional installation recommended due to complexity\u003c\/li\u003e\n\u003cli\u003eDyno tuning may be required to reach full performance potential\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-end=\"931\" data-start=\"884\"\u003eStreet Series vs Tow\/Haul vs Tow\/Haul HD\u003c\/h3\u003e\n\u003cul data-end=\"1398\" data-start=\"933\"\u003e\n\u003cli data-end=\"1099\" data-start=\"933\"\u003e\n\u003cp data-end=\"1099\" data-start=\"935\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003eStreet Series:\u003c\/span\u003e Ideal for daily driving, light work, and diesel enthusiasts.
