750+ hp @ peak rpm 680+ lb.-ft. @ peak rpm Quite simply the most powerful crate engine ever from Chevrolet Performance!
Drag racers take note! GM Performance Parts' new LSX454R crate engine delivers 750+ horsepower that will help you stay in front of the competition. More than the most powerful LS engine in our portfolio, it is the most powerful crate engine we've ever offered! Our engineers designed LSX454R for the unique, high-rpm demands of drag racing. It is a high-compression, solid-roller combination that uses our new LSX DR cylinder heads. These 11-degree, six-bolt aluminum heads feature raised ports that provide tremendous airflow. We complement them with an exclusive, high-rise open-plenum intake manifold and a Dominator-type carburetor to complete the assembly. The LSX454R's bottom end includes our LSX Bowtie cylinder block and an all-forged rotating assembly. And while we rate the engine at 750+ horsepower in its naturally aspirated form, it is capable of supporting nitrous and other power adders for even greater power. Use the LSX454R as the centerpiece of a new race car built with our 2011 Camaro body-in-white for the ultimate modern drag strip star. With 750+ horses under the hood, it will perform as good as it looks! Check out our LS1 Engine Kit Installation Guide P/N 88959384 for details on installing an LS engine in a vintage vehicle.
