LS3 Connect & Cruise – Chevy Performance 6.2L/430hp Crate Engine 6L80E (2400 Stall)

LS3 Connect & Cruise With 6L80-E Transmission (2400 Stall)

When it comes to factory-engineered performance and convenience, nothing beats Chevrolet Performance’s Connect & Cruise powertrain systems! You get the engine, automatic or manual transmission, electronic controllers and all the necessary wire harnesses all in one package. Even better, Karl Kustoms delivers it for less than the cost of buying the components separately.

Engines and transmissions are matched for optimal performance and durability, so you can wring out every last bit of horsepower with total confidence! The specially calibrated controllers are designed for retrofit installations in older vehicles, for easier and quicker installation – and more importantly – operation without the need for third-party tuning.

The Connect & Cruise lineup even includes several emissions-compliant E-ROD systems in both automatic and manual.

Important Notes

The LS3 is filled with components designed for high performance and longevity. The aluminum block is filled with a sturdy reciprocating assembly that combines with L92-type rectangular-port heads to deliver a 10.7:1 compression ratio. A high-lift, hydraulic roller camshaft complements the LS3’s tremendous airflow capability and enhances its broad torque curve. Out-of-the-crate horsepower is 430, with an impressive 425 lb.-ft. torque.

Th3 LS3 crate engine comes complete from the SS-specific oil pan to the ignition system. It also includes the intake manifold assembly with injectors and throttle body, exhaust manifolds, water pump, balancer, 58x reluctor wheel and 14-inch automatic-transmission flexplate. The SS oil pan doesn’t suit all applications. Use the vehicle-specific oil pan for original LS-powered vehicles or Chevrolet Performance’s Muscle Car Oil Pan Kit P/N 19212593 for older vehicles.
