LS-Power for your 4x4 or AWD Vehicle!

The LS3 is commonly known as the power behind the C6 Corvette and 5th generation Camaro SS, as well as the 4-door SS sport sedan. It offers the lightweight advantage of an aluminum cylinder block, aluminum heads and a composite intake manifold over the heavy cast iron engines typically used in older pickups. Reductions in weight are beneficial to old trucks as well as muscle cars and hot rods.

The LS3 is filled with components designed for stout performance and longevity. A strong reciprocating assembly topped with L92-type rectangular-port heads provide a 10.7:1 compression ratio while the hydraulic roller cam enhances the LS3’s tremendous airflow and broad torque curve. It adds up to the power you need to climb hills and traverse the trail.

The SuperMatic™ 4L70-E four-speed automatic overdrive trans. backs the LS3 with strength and durability. Based on the 4L60-E/4L65-E family of transmission with increased horsepower and torque ratings. The 4L70-E can handle up to 495 lb.-ft. of torque. Put this combo to work in your classic 4x4 project and enjoy a great balance of performance and efficiency!

The Complete Performance Package!

When it comes to factory-engineered performance and convenience, nothing beats Chevrolet Performance's industry-exclusive Connect & Cruise powertain systems. With one package you get the engine, automatic or manual transmission, electronic controllers and al the necessary wire harnesses.

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.

We did the work to design and calibrate perfectly matched powertrain systems and covered them with a 24-month / 50,000-mile limited warranty.

Chevrolet Performance pioneered the performance crate engine, so when it comes to performance innovations that save time, money and guesswork, we once again lead the way! All you have to do is install, connect, and start cruising!

NOTE: All components, engine, transmission, torque converter and controllers are ordered and delivered separately.

Connect & Cruise Builders Guide

Each Chevrolet Performance Connect & Cruise crate powertrain system includes:

  • Brand-new, fully assembled crate engine
  • Brand-new automatic or manual transmission
  • SuperMatic transmission control module and harness
  • Calibrated engine control module
  • Two oxygen sensors and mounting bosses (for installation in the exhaust system)
  • Mass airflow meter and mounting boss (for installation in the air intake system)
  • Throttle pedal assembly (for use with the electronically operated throttle)
  • Assembled wiring harness w/ fuse box and necessary cam and MAP sensor jumpers
  • Oil pressure sensor that is compatible with the harness
  • Instruction sheet

To facilitate a complete installation, the builder will need to source additional components to complete the engine assembly and get the vehicle running, including:

  • Fuel tank and fuel lines (re-circulating or returnless)
  • Fuel pump – 58 psi (400 kPa) for all engines except LSA, which requires 65 psi (450 kPa)
  • Air induction system that incorporates the mass airflow sensor

Additionally, all engines require a front-end accessory drive system. The instructions included with each kit lists recommendations and Chevrolet Performance offers several configurations to suit different applications. Each allows the installer to easily delete air conditioning.

Chevrolet Performance recommends the LS1 Engine Installation Guide P/N 88959384, which illustrates basic procedures and offers helpful tips on installing an LS engine into older vehicles.
