The DFC Diesel KORE Series Long Block was built specifically to bridge that gap, giving 2003 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 head studs, upgraded rod bolts, and Total Seal gapless piston rings. DFC also builds in improved gasket sealing methods specifically targeting the common leak points this early 6.0L 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.\u003c\/p\u003e\n\u003ch4\u003ePrecision Machining With Purposeful Upgrades To Known Weak Points\u003c\/h4\u003e\n\u003cp\u003eThe DFC Diesel KORE602003STAULB is a remanufactured long block engineered specifically for 2003 Ford F250 and F350 Super Duty trucks equipped with the 6.0L 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, along with upgraded head studs and rod bolts built to address common failure points on this early 6.0L platform. It comes standard with Total Seal gapless piston rings and incorporates improved gasket sealing methods in the areas most prone to leakage. This engine is built for models with the ICP sensor located under the turbocharger, an important distinction specific to early 2003 production. 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e 2003 Ford F250\/F350 Super Duty 6.0L Powerstroke w\/ ICP sensor under turbocharger\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFor models with the ICP sensor located under the turbocharger, confirm before ordering\u003c\/li\u003e\n\u003cli\u003eDoes not include front cover, rear cover, oil pump, upper oil pan mounting plate, oil pan, or oil pickup tube\u003c\/li\u003e\n\u003cli\u003eComponent brands may vary by build based on parts availability, cannot be specially requested\u003c\/li\u003e\n\u003cli\u003e$500 shipping charge\/$2,800 core charge \u003c\/li\u003e\n\u003cli\u003eEngine shipping crate must be returned with core engine for full core credit\u003c\/li\u003e\n\u003cli\u003eManufacturer warranty: 1 year, unlimited mileage\u003c\/li\u003e\n\u003cli\u003eOil cooler replacement highly recommended, mandatory if prior engine had a bearing failure\u003c\/li\u003e\n\u003cli\u003eInjector replacement highly recommended on higher mileage or contaminated fuel engines\u003c\/li\u003e\n\u003cli\u003eTurbocharger replacement recommended over 125K miles, mandatory if shaft play present or engine was dusted\u003c\/li\u003e\n\u003cli\u003eWater pump replacement highly recommended if engine has over 125K miles\u003c\/li\u003e\n\u003cli\u003eEvans Waterless Coolant recommended upgrade for corrosion and boilover prevention\u003c\/li\u003e\n\u003cli\u003eThis product cannot be shipped to California\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.xtremediesel.com\/mm5\/warranty\/DFC_Engines_Owners-Guide.pdf\" target=\"_blank\" rel=\"noopener\"\u003e\u003cstrong\u003eInstall Instructions\u003c\/strong\u003e\u003c\/a\u003e\u003c\/p\u003e","brand":"DFC Diesel","offers":[{"title":"Default Title","offer_id":54623549128988,"sku":"DDUKORE602003STAULB","price":6238.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/files\/60-Front_web_cd533681-cca0-4672-a1c9-edc57748f843.jpg?v=1790701197","url":"https:\/\/www.alligatorperformance.com\/products\/dfc-diesel-kore602003staulb-kore-series-long-block-std-auto-2003-ford-f250-f350-super-duty-6-0l-powerstroke","provider":"Alligator Performance","version":"1.0","type":"link"}
