FREE shipping! (48-state only.)

Chevrolet Performance has released its latest factory-engineered LS high-performance engine - the LS376/525. It blends the racing-derived ASA camshaft with the LS3 6.2L production engine to create the most powerful production-based crate engine in Chevrolet Performance's portfolio - delivering 525 horsepower at 6,200 rpm and 486 lb.-ft. at 5,200 rpm.

For installation in older vehicles, the engine controller kit part number 19354332 is calibrated specifically for this new engine.

"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 breathe 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 and the carbureted LS376/515.

"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."

Front-end accessories must be obtained separately, along with the engine controller kit. Chevrolet Performance offers several accessory drive kits to suit a variety of applications and some installations for older vehicles will require the oil pan changed.
