    Quite Simply the Most Powerful Crate Engine
    Ever from Chevrolet Performance!

    Free Shipping!

    Drag racers take note! Chevrolet Performance's LSX454R crate engine delivers 776 horsepower that will help you stay in front of the competition. More than the most powerful LS engine in their portfolio, it is the most powerful crate engine they have ever offered!

    Chevrolet engineers designed the LSX454R for the unique, high-rpm demands of drag racing. It is a high-compression, solid-roller combination that uses LSX DR cylinder heads. These 11-degree, six-bolt aluminum heads feature raised ports that provide tremendous airflow. Complemented with an exclusive, high-rise open-plenum intake manifold and a Dominator-type carburetor to complete the assembly.

    The LSX454R's bottom end includes the LSX Bowtie cylinder block and an all-forged rotating assembly. And while they rate the engine at 776 horsepower in its naturally aspirated form, we know that there is room for more.
