  • OUR MOST POWERFUL ENGINE EVER!
    Quite simply, the LSX454R drag racing engine is the most powerful crate engine ever from Chevrolet Performance - and it's designed to do one thing: help you win races with great durability.
    For the record, this 13.1:1, naturally aspirated and single Dominator-fed big-inch LS engine is officially rated at 776 horsepower at 7,000 rpm and 649 lb.-ft. of torque at 5,100 rpm. It breathes through our high-flow LSX DR six-bolt cylinder heads that have 313cc intake runners. More than power, this engine was built for durability. Its bottom end includes our tough LSX Bowtie cylinder block and it's filled with an all-forged rotating assembly.
    During development, engineers simulated the equivalent of 600 back-to-back drag strip passes on the engine dyno, ensuring it would stand up to years of performance without the need for major maintenance. It's an engine you can depend on to go round after round, season after season!
