Designed specifically for the 24-valve Storm Block, this engine doesn’t just replace your worn-out setup—it upgrades it with proven performance features made for high-load use. Whether you’re pulling trailers day in and day out or want a bulletproof long block for your next build, this package is built to handle up to 700 horsepower while keeping things reliable enough for daily duty. And unlike a basic reman, everything inside has been carefully selected, machined, and assembled to tighter tolerances using name-brand components you can trust.\u003c\/p\u003e\n\u003ch4\u003eUpgrades Where They Matter Most\u003c\/h4\u003e\n\u003cp\u003eThis build includes everything from the Street Series—like Total Seal gapless rings, Cometic MLS head gaskets, and either ARP or OptiTorque head studs—but adds a host of enhancements built specifically for towing and high-performance applications. A stage 3 camshaft improves airflow and midrange torque, while 60lb heavy-duty valve springs and Manton HD pushrods keep the top end in check under boost. The pistons are treated with ceramic-coated crowns and dry film coated skirts to manage heat and reduce wear—two must-haves in high-output, high-stress builds. From the rear aluminum freeze plug to the resurfaced and magnafluxed cylinder head, every inch of this long block is engineered with purpose. And with a 5-year\/160,000 km (100,000 mi) warranty, you’ve got long-term peace of mind to match the engine’s capability. This is the long block that lets your Cummins work as hard as you do.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFits:\u003c\/strong\u003e 1998 Dodge RAM 5.9L Cummins\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Image Note:\u003c\/strong\u003e Some images may be representative.\u003c\/p\u003e","brand":"DFC Diesel","offers":[{"title":"Default Title","offer_id":68060707553553,"sku":"DDU-TH591998SOALB","price":13894.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/0477\/1089\/files\/DDUTH591998SOALB_1.jpg?v=1794721876","url":"https:\/\/gautoparts.com\/products\/dfc-diesel-th591998soalb-tow-haul-series-speed-of-air-long-block-std-auto-1998-ram-5-9l-cummins-24v-storm-block","provider":"Guaranteed Auto Parts","version":"1.0","type":"link"}
