    The most powerful crate engine ever from Chevrolet Performance Drag racers, take note. Chevrolet Performance's new LSX454R crate engine delivers 776 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 the 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 776 horsepower in its naturally aspirated form, we know that there is room for more. Use the LSX454R as the centerpiece of a new racecar built with our Gen-V Camaro body-in-white for the ultimate modern drag-strip star. With 776 horsepower under the hood, it will perform as good as it looks!
