In addition to the 720 hp, the 7.4-liter V8 also delivers 720 lb-ft (976 Nm) of torque, thanks to a strong, all-forged rotating assembly and optimized high-rpm airflow developed by GMPP engineers. The powerplant was designed for the unique, high-rpm demands of drag racing. It offers a high-compression, solid-roller combination that uses new LSX DR cylinder heads (part number 19166979). The aluminum cylinder heads come with raised ports, that provide tremendous airflow. They are mated to the engine with an exclusive, all-new high-rise open-plenum intake manifold and a Holley 1,150-cfm Dominator carburetor.
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 racer parts, including the robust LSX Bowtie block.
“The LSX454R uses the latest LSX parts and factory-engineered technology to take LS performance to the next level. This is a great engine to use when building a cutting-edge drag car with one of our new Camaro bodies in white,” said Dr. Jamie Meyer, product integration manager for GM Performance Parts.
GM Performance Parts is the only source for brand-new classic small-block and big-block crate engines. The company is also the clear leader in “LS” performance, with a full range of production-based crate engines and the growing family of LSX maximum performance engines and parts. The LSX DR heads and matching intake manifold are also available separately.
