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 6,300 rpm and 489 lb.-ft. at 4,400 rpm.

For installation in older vehicles, the engine controller kit part number 19259261 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 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.

?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.?

As delivered, the LS376/525 includes the intake manifold, with the injectors, fuel rail and throttle body already installed, along with the water pump and ignition system. 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 to be change.
