    What Is a 6.7 Cummins Long Block?

    A 6.7 Cummins long block is the core engine assembly. It typically includes the engine block, crankshaft, connecting rods, pistons, camshaft, cylinder head, and valvetrain components. A long block does not usually include external accessories such as the turbocharger, fuel system, injectors, manifolds, sensors, wiring, or electronics.

    For many 2007.5-2018 Dodge Ram Cummins owners, replacing the engine with a long block is a better option than trying to repair a severely damaged engine. A properly built long block gives you a fresh foundation while allowing you to reuse or upgrade your external components.

    Common Reasons to Replace a 6.7 Cummins Engine

    The 6.7 Cummins is a strong platform, but high mileage, excessive heat, tuning, or fuel system issues can lead to engine failure. Common reasons customers search for a rebuilt 6.7 Cummins engine include:

    • Excessive blow-by
    • Low compression
    • Damaged pistons
    • Scored cylinder walls
    • Valve or cylinder head failure
    • Bottom-end failure
    • Coolant contamination
    • Oil consumption
    • Engine damage from injector or turbo failure

    When Should You Replace Your 6.7 Cummins Engine?

    If your engine has excessive blow-by, low compression, internal damage, or catastrophic failure, replacing it with a 6.7 Cummins long block is often the most reliable and cost-effective solution. Many Ram 2500 and Ram 3500 owners choose a long block when repair costs exceed the value of rebuilding their existing engine.

    Stock 6.7 Cummins Long Blocks vs Performance Builds

    CPP Diesel supports both stock replacement customers and performance diesel customers. A stock-style long block is a smart choice for daily drivers, work trucks, and towing applications where reliability is the main goal. A performance long block is better suited for trucks running upgraded fuel, larger turbochargers, aggressive tuning, or higher horsepower goals.

    Stock Replacement Long Block Daily driving, work trucks, towing Reliable replacement for a failed engine
    Performance Long Block Higher horsepower street and tow builds Stronger foundation for added power
    Race / Competition Engine Drag racing, sled pulling, extreme builds Built for severe use and competition demands

    6.7 Cummins Long Block FAQ

    What comes with a 6.7 Cummins long block?

    A 6.7 Cummins long block generally includes the assembled block, rotating assembly, camshaft, cylinder head, and valvetrain. External components such as the turbocharger, injectors, fuel system, manifolds, accessories, sensors, wiring, and electronics are usually not included unless stated on the product page.


    Is a 6.7 Cummins long block the same as a crate engine?

    Not always. A long block is the core engine assembly, while a crate engine may refer to a more complete engine package depending on the manufacturer or builder. Always review what is included before ordering.


    Do you offer stock and performance 6.7 Cummins engines?

    Yes. CPP Diesel supports customers looking for stock replacement engines as well as performance long blocks for higher horsepower street, towing, racing, and sled pulling applications.


    Should I replace injectors or turbochargers when installing a new long block?

    It is recommended to inspect or replace injectors, turbochargers, fuel system components, cooling system parts, and oiling system components before installing a new engine. A damaged injector or turbocharger can shorten the life of a fresh long block.
