Drop-In Crate Engine for High-Performance 6.7L Cummins' Builds

If you're building out a high-performance 6.7L Cummins, a stock engine just isn’t going to cut it. Factory internals weren’t designed to handle extreme horsepower, high boost levels, or aggressive fueling. So, if you’re looking for an engine that can take serious power without sacrificing durability, the BD Diesel Street Performance Long Block is built for the job. Whether you're running a high-horsepower street truck, competing on the track, or pushing your setup to the next level, this engine gives you the foundation you need for reliable, high-performance power. At the core of this build are D&J X-Beam billet connecting rods, a major upgrade over the stock rods, which can fail under extreme cylinder pressure. These billet rods are built to handle high horsepower applications, providing the strength needed to withstand heavy fueling and high RPMs. If you’re pushing for four-digit horsepower numbers, these rods ensure your bottom end stays intact, even under extreme conditions.

High-Quality Sealing with Impressive Airflow Impropvement

Keeping the cylinder head sealed is critical when running high boost, which is why this engine features a fire-ringed cylinder head with custom-machined grooves. This setup creates a superior seal between the head and block, reducing the risk of head gasket failure—one of the most common weak points in high-horsepower diesel builds. Combined with ARP 9/16” head studs, this engine is designed to hold up under extreme boost levels without lifting the head or causing sealing issues. Airflow is just as important as durability, and this long block delivers with a Stage 1 High-Performance Cylinder Head. Featuring 5-axis CNC porting, oversized intake and exhaust seats, and heavy-duty bronze valve guides, this head is optimized for better airflow, allowing your engine to breathe more efficiently. The result is improved throttle response, lower EGTs, and better overall performance, whether you’re daily driving, drag racing, or pushing the truck hard at the dyno.

Perfectly Engineered for your Ride

Every component in this engine has been precision-machined, balanced, and blueprinted to ensure maximum reliability on your tough Ram Truck. Unlike a standard rebuild that reuses old parts, this long block is built from the ground up with brand-new pistons, bearings, tappets, and a fully upgraded oiling system. This eliminates the risk of worn components causing premature failure, giving you a fresh, high-strength foundation for any high-performance build. Installation is simple, thanks to the fully assembled, pre-lubed design. The engine comes ready to drop in with an oil pan, front cover, and machined rocker box included. Pre-lubed with break-in oil, it ensures a smooth first startup without the hassle of prepping components yourself. Designed as a direct replacement for 2007.5-2012 Ram 6.7L Cummins applications, this long block saves you time and effort compared to a complete rebuild.
