Chevy Ls Swap Guide: Achieving 550 Hp with Comp Cams Camshafts and Edelbrock Intake

by

The Chevy LS engine has become a favorite among car enthusiasts and builders due to its versatility and performance potential. In this guide, we will explore how to achieve 550 horsepower using Comp Cams camshafts and an Edelbrock intake manifold. This combination not only enhances performance but also ensures reliability and drivability.

Understanding the Chevy LS Engine

The LS engine family, introduced in 1997, is known for its lightweight design and robust power output. Key features include:

  • Aluminum construction for reduced weight.
  • Modular design allowing for easy upgrades.
  • Wide availability of aftermarket parts.

Choosing the Right Components

To achieve 550 hp, selecting the right components is crucial. The two main components we will focus on are:

  • Comp Cams Camshafts: Known for their performance-oriented designs, they provide the necessary lift and duration for increased horsepower.
  • Edelbrock Intake Manifold: This intake improves airflow, enhancing engine efficiency and power output.

Comp Cams Camshafts

Comp Cams offers a variety of camshafts tailored for LS engines. When selecting a camshaft, consider the following:

  • Lift: Higher lift allows more air into the engine.
  • Duration: Longer duration helps maintain power at higher RPMs.
  • LSA (Lobe Separation Angle): Affects the engine’s idle characteristics and power band.

For achieving 550 hp, consider the following camshaft profiles:

  • Comp Cams Xtreme Energy 224/224
  • Comp Cams Stage 2 Truck Cam
  • Comp Cams NSR (No Springs Required) Cam

Edelbrock Intake Manifold

The Edelbrock intake manifold is designed to optimize airflow, which is essential for maximizing horsepower. Key features include:

  • High Flow Design: Increases the volume of air entering the engine.
  • Lightweight Material: Reduces overall engine weight.
  • Compatibility: Works well with a variety of LS engine configurations.

Engine Build Process

Now that we have our components, let’s discuss the build process to achieve 550 hp:

  • Step 1: Disassemble the engine and remove the stock camshaft.
  • Step 2: Install the Comp Cams camshaft, ensuring proper alignment and lubrication.
  • Step 3: Replace the intake manifold with the Edelbrock unit, ensuring a proper seal.
  • Step 4: Reassemble the engine, paying attention to torque specifications.
  • Step 5: Tune the engine using a performance ECU for optimal performance.

Tuning for Performance

After the installation is complete, tuning is essential to unlock the full potential of your LS engine. Consider the following:

  • ECU Calibration: Adjust fuel maps and ignition timing for optimal performance.
  • Dyno Testing: Use a dynamometer to measure horsepower and torque output.
  • Fine-Tuning: Make adjustments based on dyno results to achieve the desired horsepower.

Final Thoughts

Achieving 550 hp with a Chevy LS engine using Comp Cams camshafts and an Edelbrock intake is a rewarding project. With the right components and careful tuning, you can enjoy a powerful and reliable engine build that enhances your vehicle’s performance.

Always remember to consult with professionals and follow best practices during your build to ensure safety and performance.
