Chevy Performance LS3 Connect & Cruise Powertrain System – 6.2L 2WD Engine with 4L70E Automatic Transmission

LS3 Connect & Cruise with 4L70-E Transmission

This LS3 Connect & Cruise crate engine brings Corvette or Camaro power straight to your project vehicle. The LS3 is the power behind the C6 Corvette and 5th generation Camaro SS. It offers the lightweight advantage of an aluminum cylinder block, aluminum heads, and a composite intake manifold over the heavy cast iron engines used in early cars. Reductions in frontal weight are beneficial to the overall balance and performance of your hot rod or muscle car. With one package you get the engine, automatic transmission, electronic controllers and all the necessary wire harnesses – all delivered for less than the cost of buying the components separately.

Inside, this LS3 is filled with components designed for high performance and longevity. A sturdy reciprocating assembly combines with L92-type rectangular-port heads to deliver a 10.7:1 compression ratio. A high-lift, hydraulic roller camshaft with 0.551-inch of lift on the 2.16-inch intake valves and 0.522-inch lift on the 1.59-inch exhaust valves, enhances its tremendous airflow and broad torque curve.

Chevy’s engines and transmissions are matched for optimal performance and durability, so you can push for every possible bit of horsepower with total confidence! The specially calibrated controllers are designed for retrofit installations in older vehicles, for easier and quicker installation and for operation without the need for 3rd party tuning.

Chevrolet’s Connect & Cruise lineup includes several emissions-compliant E-ROD systems available in both automatic and manual. Each system is designed and calibrated to perfectly match the engine powertrain systems and is covered by a 24-month / 50,000-mile limited warranty. When it comes to performance innovations that save time, money and guesswork, Chevy crate engines and Connect-and-Cruise systems lead the way – just install, connect, and start cruising.

Important Notes

For 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, this engine requires 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. Note that exhaust manifolds are NOT INCLUDED.

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