It’s built for drivers who count on their trucks day in and day out and want an engine that can hold up without question. One of the biggest highlights here is the forged Callies crankshaft, which brings serious strength and long-term reliability to your bottom end. Add to that a full list of upgraded internals and high-quality machine work, and you're looking at a long block that’s made to last. Whether you're hauling loads across town or running your truck as a daily driver, this engine is built to outperform the stock LLY in all the ways that matter. It also comes with a 5-year, 160,000 km warranty, so you can stop worrying and focus on putting your truck to work. It’s more than a replacement, it’s a serious step up from factory performance.\u003c\/p\u003e\n\u003ch4\u003ePrecision Built For Demanding Duramax LLY Applications\u003c\/h4\u003e\n\u003cp\u003eThe DFC SS6604505LLYTKSOALBCC Street Series Long Block is built with exacting standards and premium-grade components designed for the 6.6L Duramax LLY platform in 2004.5-2005 TopKick models. At the center of this build is a forged Callies crankshaft, known for its excellent balance and durability under load. The block itself is machined to accept the next oversize pistons, with all-new internals including rings, bearings, seals, and gaskets that meet or exceed OEM specifications. The cylinder heads are fully remanufactured with new guides, seats, valves, and stem seals, then resurfaced and magnafluxed to ensure strength and sealing integrity. ARP or OptiTorque head studs are used to clamp everything together, depending on availability, while Total Seal gapless rings are installed to improve combustion and reduce oil loss. The woodruff keyed camshaft and EDM doweled oil pump gear are thoughtful touches that help eliminate known weak points in factory builds. This long block also arrives with pre-set rockers and pushrods and a complete top-end gasket kit to make installation more straightforward and efficient.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e Fits: \u003c\/strong\u003e 2004.5, 2005 GM\/Chevrolet 2500HD\/3500HD 6.6L Duramax LLY\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eEngine is designed specifically for 2004.5-2005 GM\/Chevy TopKick models with the 6.6L Duramax LLY\u003c\/li\u003e\n\u003cli\u003eStreet Series is ideal for daily use, diesel enthusiasts, and general work applications\u003c\/li\u003e\n\u003cli\u003eFeatures a forged Callies crankshaft for increased bottom-end strength\u003c\/li\u003e\n\u003cli\u003eAll internal components are new or meet OEM or better standards\u003c\/li\u003e\n\u003cli\u003eIncludes fully remanufactured cylinder heads with all new seats, valves, guides, and stem seals\u003c\/li\u003e\n\u003cli\u003eBlock is bored to accept next oversize pistons for proper fitment\u003c\/li\u003e\n\u003cli\u003eUses ARP or OptiTorque head studs depending on supply availability\u003c\/li\u003e\n\u003cli\u003eMachined using advanced Rottler equipment to ensure precision tolerances\u003c\/li\u003e\n\u003cli\u003eNot a complete engine, external accessories, turbo, ECM, and fuel system components not included\u003c\/li\u003e\n\u003cli\u003eIncludes a complete top-end gasket kit for installation\u003c\/li\u003e\n\u003cli\u003eComes with DFC's industry-leading 5-year or 160,000 km limited warranty\u003c\/li\u003e\n\u003cli\u003eProfessional installation is recommended to ensure proper function and warranty compliance\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\u003cstrong\u003e\u003cspan style=\"text-decoration: underline;\"\u003eStreet Series:\u003c\/span\u003e Ideal for daily driving, light work, and diesel enthusiasts.
