"This is a terrific engine combination that illustrates perfectly the performance potential of the LS engine family - and how it can be enhanced dramatically at an affordable price," said Jim Campbell, GM U.S. vice president of Performance Vehicles and Motorsports. "Whether you've got a new Camaro or a classic Chevelle, this engine delivers terrific bang for the buck."
Using the LS3 production engine - the same used in Corvettes and Camaros - as the foundation for the LS376/525 helped keep the retail price lower, while the ASA camshaft is a proven, power-building component that has been successful in the high-rpm world of circle track racing.
The ASA camshaft is a hydraulic roller with .525-inch lift on both the intake and exhaust sides, along with 226 degrees duration on the intake side and 236 degrees on the exhaust side. Coupled with a tight, 110-degree lobe separation angle, it helps the engine deliver excellent throttle response and breath exceptionally well at high rpm.
The cam also gives the LS376/525 the most aggressive personality among Chevrolet Performance's growing lineup of production-based high-performance crate engines, which also includes the LS376/480 (part number 19419864) and the carbureted LS376/515 (part number 19419868).
"The LS376/525 engine has an edge to it," said Campbell. "You'll notice it in the idle quality and you'll feel it when the revs quickly climb."
