The LS3 engine matched with the ASA camshaft creates a crate engine with an edge

LAS VEGAS – 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.

The LS376/525 is available under part number 19259233 and carries a suggested retail price of $8,937.50. 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. Chevrolet Performance complements this high-performance camshaft in the engine with higher-rate valve springs.

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 19244549) and the carbureted LS376/515 (part number 19171225).

“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 Chevrolet Performance’s Muscle Car Oil Pan Kit, part number 19212593.

Chevrolet Performance also recommends the LS1 Engine Kit Installation Guide – part number 88989384 – which outlines the basics of LS engine swaps in older vehicles.
