Heavy-Duty Long Block Designed for Hardcore Hauling Applications

If your truck is built for towing, hauling, or putting down serious power, your engine needs to be just as tough. A stock 6.7L Cummins is a workhorse, but when you start pushing heavy loads or running higher boost, factory components can become a weak link. Instead of dealing with the hassle of a complete rebuild or risking a failure at the worst possible time, the BD Diesel Heavy Hauler Long Block gives you a fully assembled, high-strength engine designed specifically for demanding applications. Built for durability, efficiency, and performance, this long block is the ultimate upgrade for hardworking trucks. One of the key improvements in this build is the precision CNC machining. Every engine is fully blueprinted, bored, honed, and torque plate honed to ensure exact tolerances. This process strengthens the block, improves piston sealing, and reduces wear over time. Whether you’re running your truck in stock form or with tuning and supporting mods, this level of precision helps maintain reliability under heavy loads and extreme conditions.

Superior Airflow and Heat Management

Airflow is another area where this engine outperforms stock. The D&J Stage 1 High-Performance Cylinder Head features 5-axis CNC porting and extra-large heavy-duty valve seats, allowing the engine to breathe better and run more efficiently. The improved airflow not only boosts power but also helps lower exhaust gas temperatures, which is crucial for towing and long highway pulls. A well-flowing head reduces strain on the turbo and improves overall engine longevity. What's more, heat is the enemy of performance and reliability, especially when you’re pushing a truck hard. This long block comes with a street/towing camshaft designed to lower EGTs by 200-300 degrees. By optimizing the engine’s efficiency, it not only reduces heat buildup but also improves fuel economy—a major benefit for trucks that spend long hours on the road or under load.

Impressive Sealing Capabilities

To keep everything sealed under high boost, BD Diesel equips this engine with custom ARP 9/16” head studs. These provide superior head-to-block clamping force, preventing head gasket failures that are all too common in high-performance diesel applications. Whether you're running a stock turbo or a larger aftermarket setup, this upgrade ensures long-term reliability even under extreme cylinder pressures. For convenience, this long block comes fully assembled and pre-lubed with break-in oil, so it’s ready to install right out of the crate. It includes an oil pan, front cover, and rocker box, making it a direct replacement for 2013-2018 Ram 6.7L Cummins applications. Instead of spending weeks tracking down parts and waiting on machine work, you can drop this engine in and get your truck back to work with minimal downtime.
