GRAND BLANC, Mich. – GM Performance Parts’ (GMPP) announces the all-new LSX454R crate engine (part number 19257880), a 720-horsepower drag racing engine that is the most powerful small-block V-8 engine ever engineered by General Motors.

The LSX454R is officially rated at 720 horsepower and 720 lb.-ft. of torque, with a very strong, all-forged rotating assembly and optimized high-rpm airflow developed by GMPP engineers.

“The LSX454R uses the latest LSX parts and factory-engineered technology to take LS performance to the next level,” said Dr. Jamie Meyer, product integration manager for GM Performance Parts. “This is a great engine to use when building a cutting-edge drag car with one of our new Camaro bodies in white.”

Growth in the popularity of LS-based drag racing helped drive the design and development of the LSX454R. It brings together many of the specialized GMPP LSX parts racers are already using, including the robust LSX Bowtie block, and offers a ready-built engine that is competitive out of the crate.

GMPP engineers designed the LSX454R for the unique, high-rpm demands of drag racing. It is a high-compression, solid-roller combination that uses new LSX DR cylinder heads (part number 19166979). The 11-degree, six-bolt aluminum heads feature raised ports that provide tremendous airflow. They are matched on the engine with an exclusive, all-new high-rise open-plenum intake manifold and a Holley 1,150-cfm Dominator carburetor.  

The LSX DR heads and matching intake manifold are available separately.
