Chevrolet Performance announced the LSX454R crate engine (part number 19257880) goes on sale in December 2011, just in time for the 2012 racing season.

GM Performance Parts (GMPP) auctioned the first production LSX454R crate engine Jan. 21 at the Barrett-Jackson auction in Scottsdale, Arizona. The winning bid was $67,000 with the proceeds going to the American Heart Association. 

Rated at 750 horsepower and 680 lb.-ft. of torque, it’s the most powerful small-block V-8 engine ever engineered by Chevrolet and is designed expressly for the rigors of competitive drag racing.

“The LSX454R offers a ready-built engine that is competitive out of the crate,” said Jim Campbell, GM U.S. vice president of Performance Vehicles and Motorsports. “By using the latest LSX parts and factory-engineered technology, we’ve taken LS performance to the next level that will make racers competitive the moment they install this engine.”

Growth in the popularity of LS-based drag racing helped drive the development of the LSX454R. It brings together many of the specialized Chevrolet Performance LSX parts racers are already using, including the robust LSX Bowtie block, and matches them with a very strong, all-forged rotating assembly and specially designed cylinder heads. The heads deliver tremendous airflow at high rpm – right where a drag racing engine needs it the most to make horsepower.

The LSX454R is also engineered to deliver dependable high-performance. And while there is no warranty on this racing engine, Chevrolet Performance engineers developed a special durability testing process that meets consumer expectations.

“GM engineers developed a unique schedule to validate the LSX454R to the equivalent of 600 drag-strip passes when maintained with regular maintenance schedules and run to Chevrolet’s prescribed operating parameters for the engine,” said Steve Felix, development engineer. “Chevrolet Performance got its start developing racing engines and parts, so we have a long, established legacy of developing durable products that help our customers win.”
