The DFC Diesel KORE Series Short Block gives 2006.5-2007 Super Duty owners a remanufactured foundation built to correct the weak points that plague these engines from the factory. During the build, DFC specifically targets known failure areas like the main caps, adding a bead of silicone at that joint to eliminate a common leak path before it ever becomes a problem. Every short block is machined using Rottler equipment, delivering tolerances tighter than OEM specifications, and rebuilt with near identical weight piston and connecting rod assemblies for a smoother, more balanced running engine. Inside, you're getting all new pistons, rings, bearings, and rods, giving your rebuild real internal integrity rather than reused, worn components. The engine ships with 20mm head dowels, an important detail for anyone matching this block to the correct head gasket and cylinder head setup. Whether you're finally addressing a tired 6.0L for good or building toward a more serious future upgrade, this short block gives you a dependable place to start.\u003c\/p\u003e\n\u003ch4\u003ePrecision Machining With Purposeful Upgrades To Known Weak Points\u003c\/h4\u003e\n\u003cp\u003eThe DFC Diesel KORE600607STAU20SB is a remanufactured short block engineered specifically for 2006.5-2007 Ford F250 and F350 Super Duty trucks equipped with the 6.0L Powerstroke engine, compatible with both standard and automatic transmission applications. Every short block is machined using Rottler equipment, delivering tolerances that exceed OEM specifications throughout the build. During remanufacturing, DFC addresses known risk points on this platform, including adding a bead of silicone at the main caps to help eliminate a common source of leaking. The short block includes all new pistons, rings, bearings, and rods, along with reinforced internals designed to reduce noise and improve overall engine balance. This short block is built with 20mm head dowels, so confirming your cylinder head and gasket setup matches this dowel specification is an important step before installation. The package includes a new oil pan and a complete gasket kit to support installation, though as a short block it does not include the cylinder head, which must be sourced or reused separately. 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 2006.5, 2007 Ford F250\/F350 Super Duty 6.0L Powerstroke 20mm head dowels\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThis is a short block only, cylinder head not included\u003c\/li\u003e\n\u003cli\u003eBuilt with 20mm head dowels, confirm head and gasket compatibility before ordering\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":54623398363420,"sku":"DDUKORE600607STAU20SB","price":4051.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/files\/DFC_03-07_6-0_Short-Block_web_600x600_2.webp?v=1790697579","url":"https:\/\/www.alligatorperformance.com\/products\/dfc-diesel-kore600607stau20sb-kore-series-long-block-std-auto-2006-5-2007-ford-f250-f350-super-duty-6-0l-powerstroke-20mm-dowels","provider":"Alligator Performance","version":"1.0","type":"link"}
