by

Building a 600 HP Chevy LS swap can be an exciting project for automotive enthusiasts looking to boost performance. This guide will cover essential components such as heads, camshafts, and supporting modifications to help you achieve your horsepower goals.

Understanding the Chevy LS Engine

The Chevy LS engine family is known for its lightweight design, compact size, and impressive performance capabilities. These engines have gained popularity in the automotive world due to their versatility and potential for high horsepower builds.

Choosing the Right Cylinder Heads

Cylinder heads play a crucial role in the performance of your LS engine. Selecting the right heads can significantly impact airflow, combustion efficiency, and overall power output.

Factors to Consider

  • Material: Aluminum heads are lighter and dissipate heat better than cast iron heads.
  • Port Size: Larger ports can improve airflow but may sacrifice low-end torque.
  • Combustion Chamber Size: Smaller chambers increase compression, leading to more power.
  • Valves: Bigger valves can enhance airflow but may require additional modifications.
  • LS3 Heads: Known for their excellent airflow and performance.
  • LS6 Heads: A great option for a balance between performance and cost.
  • AFR Heads: High-performance aftermarket heads that provide significant gains.

Selecting the Right Camshaft

The camshaft is another critical component that influences engine performance. It controls the timing and duration of valve openings, affecting horsepower and torque characteristics.

Camshaft Specifications

  • Lift: Higher lift allows more air and fuel into the engine.
  • Duration: Longer duration can increase peak power but may reduce low-end torque.
  • Lobe Separation Angle: Affects the engine’s idle quality and power band.
  • Texas Speed Stage 2: A popular choice for achieving 600 HP.
  • Brian Tooley Racing Cam: Known for excellent performance and drivability.
  • Comp Cams XFI: Designed for high horsepower applications.

Supporting Modifications

To reach 600 HP, it’s essential to consider supporting modifications that enhance engine performance and reliability. These modifications can help optimize the combination of heads and camshaft.

Essential Upgrades

  • Intake Manifold: A high-performance intake can improve airflow to the engine.
  • Fuel System: Upgrading fuel injectors and pump ensures adequate fuel delivery.
  • Exhaust System: A free-flowing exhaust reduces back pressure and enhances performance.
  • Tuning: Proper tuning is crucial to maximize the potential of your engine setup.

Additional Considerations

  • Cooling System: An upgraded radiator and fans can help manage engine temperatures.
  • Transmission: Ensure your transmission can handle the increased power.
  • Rear End: A stronger rear end is necessary for reliable power transfer.

Final Thoughts

Building a 600 HP Chevy LS swap is an ambitious yet rewarding project. By carefully selecting the right heads, camshaft, and supporting modifications, you can create a powerful and reliable engine that meets your performance goals. Always remember to conduct thorough research and consider the entire system for optimal results.
