Are you looking for an engine that can not only handle power but is also reliable? The Street Performance Long Block from D&J Precision Machine is designed for trucks that see real use, real loads, and real horsepower. This isn’t a basic rebuild; it’s a fully assembled engine built to support higher boost, aggressive tuning, and the demands of daily use.

This setup is all about balance. It delivers stronger throttle response, more consistent performance under load, and the confidence that your engine won’t become the weak link once you turn things up. Whether you’re building a tow rig, a daily driver, or a high-performance street truck, this is the kind of foundation that lets you actually use the power you have added.

Built from the ground up as a complete long block, this engine comes fully assembled from the oil pan to the top end, simplifying installation and ensuring consistency right out of the crate.

What sets the Street Performance series apart is the upgraded internal hardware and airflow-focused design. These engines are built to handle significantly higher cylinder pressure and boost levels than stock, incorporating strengthened rotating assembly components and performance cylinder head upgrades to improve airflow and durability.

The result is a long-block, high-demand diesel engine that delivers improved strength, better airflow, and long-term reliability while still maintaining everyday-use capabilities.
