The Chevy LS swap is a popular choice among automotive enthusiasts looking to boost performance and reliability. One of the most effective ways to achieve significant horsepower gains is by utilizing LS3 heads paired with an Edelbrock supercharger. In this guide, we will explore the steps necessary to complete a successful LS swap while achieving an impressive 650 horsepower.
Understanding the LS Engine Family
The LS engine family, introduced in 1997, has become a favorite among car builders and racers due to its lightweight design, durability, and extensive aftermarket support. The LS3 engine, in particular, is known for its high performance and efficiency, making it an ideal candidate for a swap.
Key Components for the LS Swap
- LS3 engine block
- LS3 cylinder heads
- Edelbrock supercharger kit
- Fuel system upgrades
- Exhaust system modifications
- Transmission compatibility
Step-by-Step LS Swap Process
1. Preparation and Planning
Before beginning the swap, it’s crucial to have a clear plan. Gather all necessary tools and components, and ensure you have a suitable workspace. Research the specific requirements for your vehicle model, as each may have unique challenges.
2. Removing the Old Engine
Start by disconnecting the battery and removing any components that may obstruct the engine removal, such as the radiator, exhaust, and wiring harness. Carefully detach the engine mounts and use an engine hoist to lift the old engine out of the vehicle.
3. Installing the LS3 Engine
Position the LS3 engine in the engine bay and secure it to the engine mounts. Ensure that the engine is level and properly aligned with the transmission. Reconnect any necessary components, including the wiring harness and fuel lines.
4. Adding LS3 Heads and Edelbrock Supercharger
Once the engine is in place, install the LS3 cylinder heads. Follow the manufacturer’s specifications for torque settings to ensure a proper seal. Next, install the Edelbrock supercharger kit, which includes the supercharger itself, intake manifold, and necessary hardware.
5. Upgrading the Fuel System
To support the increased power output, upgrade the fuel system with high-performance injectors and a fuel pump capable of delivering the required fuel flow. Ensure that the fuel lines are compatible with the new components.
6. Modifying the Exhaust System
The LS3 engine and supercharger will require a free-flowing exhaust system to maximize performance. Consider installing headers and a high-performance cat-back exhaust system to improve airflow and enhance sound.
7. Finalizing the Installation
After all components are installed, double-check all connections and fasteners. Reconnect the battery and perform a thorough inspection of the engine bay before starting the engine for the first time.
Tuning for Maximum Performance
Once the engine is installed and running, it is essential to have the vehicle tuned to achieve optimal performance. A professional tuner can adjust the engine’s air-fuel ratio, ignition timing, and other parameters to ensure the engine operates efficiently and reliably at 650 horsepower.
Conclusion
Achieving 650 horsepower with an LS3 engine and Edelbrock supercharger is a rewarding project for any automotive enthusiast. By following the steps outlined in this guide, you can successfully complete an LS swap and enjoy the benefits of increased power and performance.
