Chevrolet Performance LS3 495HP Engine w/4L70E 2WD Transmission Package CPSLS3764804L70E

New Connect and Cruise Package

Chevrolet Performance is breaking new ground in 2012 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:
• LS3 495HP Engine
• Engine Controller
• 4L70E Transmission with Torque Converter
• Transmission Controller
• 4L70E Install Kit

The hot new small block V8 in the GM lineup is the hyper-aggressive LS3. It offers a high-revving 376-inch combination that represents generations of small block V8 development and engineering. Not only is the LS3 an amazing engine in its stock configuration, but with those high-flowing rectangular port cylinder heads, the LS3 is loaded with potential. To tap into this potential, the engineers at Chevrolet Performance Parts offer you the LS 376/495 - an LS3 with an upgraded camshaft that ups power by a whopping 50 horsepower!

The LS 376/495 comes with the same great features as the LS3 crate engine. The bottom end includes a 6-bolt aluminum block, nodular crank, high performance rods, and 10.7:1 pistons. The heads are high-flowing rectangular-port units that share their design with the amazing LS7. The same EFI intake manifold feeds the hungry engine, while 1.7:1 roller rockers work with the upgraded camshaft.

The Chevrolet Performance Parts engineers picked the LS Hot Cam (p/n 12617570) to take the LS3 to the next level. This cam specs out with .525-inch intake and exhaust valve lift. Duration (@ .050 inches) is 219 intake and 228 exhaust. This cam allows for a dramatic increase in power across the power band while still maintaining good street manners. The engine will idle and cruise just like an LS3, but the power increase is there whenever you need it.

With all of the same great components as the LS3, but with an additional 50 horsepower, the new LS 376/495 is ready, willing, and able to answer your call for a new LS crate engine.
