Designed to support up to 900 horsepower, this engine brings serious muscle to the table without sacrificing everyday reliability. It’s built for the kind of work that punishes weak components, whether that’s hauling a trailer through the mountains or putting power down on the open highway. With upgrades like a balanced rotating assembly, HD flexplate, and a new OEM balancer, you get the confidence to push your 6.0L Powerstroke further than ever. The forged connecting rods, Wagler or Carrillo depending on availability, give the bottom end the durability needed for high-stress towing or weekend performance. DFC even backs this engine with a 5-year, 160,000km warranty, so you know it’s made to last. If you're running a 2004 F250 or F350 and want a serious upgrade without cutting corners, this long block is built for the job.\u003c\/p\u003e\n\u003ch4\u003eBuilt For High Output With Proven Internal Strength\u003c\/h4\u003e\n\u003cp\u003eThe Tow\/Haul HD Series is DFC Diesel’s most advanced 6.0L Powerstroke long block, engineered to handle higher power levels while retaining long-term drivability. It’s built using a professionally machined and bored block fitted with oversized pistons and remanufactured heads that are magnafluxed, resurfaced, and rebuilt with new guides, valves, seats, and stem seals. All components meet or exceed OEM specs, including the new pistons, rings, and gaskets that ensure consistent compression and durability. Internally, the rotating assembly is balanced and strengthened with forged connecting rods from either Wagler or Carrillo, depending on availability. ARP connecting rod bolts and either ARP 2000 or OptiTorque head studs further reinforce the structure to withstand serious cylinder pressures. You’ll also get a complete short block, top-end gasket kit, and pre-installed rockers and pushrods to streamline the install process. This engine is ideal for 2004 F250 and F350 owners who want a high-performance diesel platform that can keep up with demanding towing and hauling needs.\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 900 HP at the flywheel\u003c\/li\u003e\n\u003cli\u003eOptimal towing power range is 500 to 750 HP\u003c\/li\u003e\n\u003cli\u003eIncludes all upgrades from Street and Tow\/Haul Series\u003c\/li\u003e\n\u003cli\u003eForged rods may be Wagler or Carrillo based on availability\u003c\/li\u003e\n\u003cli\u003eBalanced rotating assembly improves performance and engine life\u003c\/li\u003e\n\u003cli\u003eComes with new OEM balancer and HD flexplate\u003c\/li\u003e\n\u003cli\u003eBuilt using new OEM or equivalent pistons, rings, and gaskets\u003c\/li\u003e\n\u003cli\u003eRemanufactured heads are magnafluxed, resurfaced, and rebuilt\u003c\/li\u003e\n\u003cli\u003eBlock is machined and bored for oversized pistons\u003c\/li\u003e\n\u003cli\u003eIncludes complete gasket kit, cylinder heads, and valve components\u003c\/li\u003e\n\u003cli\u003eBacked by a 5-year, 160,000km manufacturer warranty\u003c\/li\u003e\n\u003cli\u003eProfessional installation is highly recommended\u003c\/li\u003e\n\u003cli\u003eDesigned specifically for 2004 F250 and F350 6.0L Powerstroke models\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.
