New Connect and Cruise Package
Chevrolet Performance is breaking new ground with the launch of the new Connect-and-Cruise crate powertrain systems. They're factory-engineered engine-and-transmission combinations that include all the electronic control modules, wiring harnesses and other key components you need with the simplicity of one part number. Our engineers matched the engines and transmissions for optimal performance and durability, so you can wring out all the horsepower from them with total confidence. The specially calibrated controllers are designed for retrofit installation in older vehicles, for easier and quicker installation and operation, without the need for third-party tuning. Each one comes with an installation kit, including flex plates, covers and other important components to keep typical mid-project parts chasing to a minimum.
Engine and Trans Includes:
• 19301360 LS3 525HP Engine
• 19259261 Engine Controller
• 4L70E Transmission with Torque Converter
• Transmission Controller
• 4L70E Install Kit
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. 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.
