    • 6.7L 24V Cummins Long Blocks (2007.5–2018)

    If you are replacing or rebuilding a 2007.5-2018 Dodge Ram engine, our 6.7L 24V Cummins long blocks provide a reliable and more complete engine solution. A long block is the ideal choice when you need more than a short block and want a fully assembled top-end included. This reduces installation time, minimizes parts transfer, and gives you a dependable foundation for stock replacement, towing applications, work trucks, and performance builds.

    Compared to a short block, a 6.7 Cummins long block includes the cylinder head and valvetrain components, making it the better option when your existing top-end parts are worn, damaged, or no longer worth reusing. It provides a strong balance between cost and convenience, helping you get back on the road faster without stepping up to a full crate engine. Whether you are rebuilding a daily driver, maintaining a fleet vehicle, or building a durable towing or performance setup, CPP Diesel helps simplify the process with dependable Cummins engine options and real diesel experience.

    Shop our 2007.5-2018 6.7L Cummins long blocks below and choose the configuration that fits your project. If you are looking for a more budget-friendly bottom-end solution, compare our 6.7L Cummins short blocks. For complete drop-in replacement options across multiple generations, explore our reman Cummins engine options to find the right setup for your truck and budget.

    What Comes In A 6.7 Cummins Long Block?

    A 6.7 Cummins long block includes the engine block, crankshaft, pistons, bearings, cylinder head, and valvetrain components, professionally assembled and ready for installation. This gives you a more complete engine package than a short block while still allowing flexibility for fuel system components, turbochargers, manifolds, and accessories. For many builds, a long block offers the ideal balance between installation simplicity, cost, and long-term reliability.

    Long Block Vs Short Block Cummins Engines

    A long block includes both the bottom end and the cylinder head assembly, while a short block includes only the lower rotating assembly. If your cylinder head or valvetrain components are worn or questionable, a long block is typically the better option because it reduces installation time and limits the need for additional parts. If your top-end components are still in good condition and you want to reduce cost, a short block may be the better choice depending on your build goals.
