The DFC Diesel Kore Series Long Block is built specifically for the 1998 model year Storm Block, and DFC's engine builders remanufacture every unit to meet strict tolerances that actually exceed factory specifications. Using Rottler machining equipment, DFC brings each long block back to tighter, more precise dimensions than what left the factory originally, which translates to a smoother running engine with less noise and better overall balance. Inside, you're getting new pistons, rings, bearings, and rods, along with reinforced internals designed to hold up to real work rather than just meet a minimum spec. The kit arrives as a complete short block assembly with the cylinder head already included, along with a top end gasket kit and rockers and pushrods preset to factory specifications, so your installer isn't left tracking down extra pieces mid-build. Whether your original block finally gave out from age or you're restoring a tired 12 valve back to dependable daily service, this long block gives you a genuine fresh foundation rather than a patched-together repair. For an engine platform this respected among diesel owners, that fresh start matters.\u003c\/p\u003e\n\u003ch4\u003ePrecision Remanufacturing Built Around 1998 Storm Block Specifications\u003c\/h4\u003e\n\u003cp\u003eThe DFC Diesel KORE591998LB is a remanufactured long block engineered specifically for the 1998 Dodge Ram 2500 and 3500 equipped with the 5.9L Cummins 12 valve engine using the Storm Block casting. Every long block is remanufactured using Rottler machining equipment, allowing DFC to hold tolerances tighter than original OEM specifications during the rebuild process. The assembly is rebuilt using near identical weight piston and connecting rod assemblies, which helps maintain proper engine balance and reduces vibration and noise compared to mismatched aftermarket internals. New components include pistons, rings, bearings, and rods, and the long block ships as a complete short block assembly including the cylinder head, all necessary gaskets, and a top end gasket kit for completing the install, with rockers and pushrods already preset to factory specifications. Every engine is manufactured in an ISO 9001:2015 certified facility, reflecting a consistent quality management process across the build. DFC notes that specific component brands used during remanufacturing may vary based on parts availability at the time of each build, since components are sourced from multiple trusted brands at DFC's discretion and cannot be specially requested. This long block is backed by a manufacturer warranty of 5 years or 100,000 miles for standard use, or 1 year and 19,000 miles for commercial applications.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e 1998 Dodge RAM 2500\/3500 5.9L Cummins (24V Storm Block)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThis engine is specifically for 1998 models with the Storm Block only\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: 5 year\/100,000 miles standard, 1 year\/19,000 miles commercial\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\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\" rel=\"noopener\" target=\"_blank\"\u003e\u003cstrong\u003eInstall Instructions\u003c\/strong\u003e\u003c\/a\u003e\u003c\/p\u003e","brand":"DFC Diesel","offers":[{"title":"Default Title","offer_id":54605412466972,"sku":"DDUKORE591998LB","price":5050.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0738\/2279\/8108\/files\/dfc-diesel-soa-street-series-long-block-crate-engine-1998-dodge-5.9l-12v-cummins-24v-storm-block-ss591998soalb__40063.webp?v=1790267376","url":"https:\/\/www.alligatorperformance.com\/products\/dfc-diesel-kore591998lb-12v-kore-series-long-block-std-auto-1998-dodge-ram-2500-3500-5-9l-cummins-24v-storm-block","provider":"Alligator Performance","version":"1.0","type":"link"}
