by

The Chevy LS engine has become a staple in the automotive world, renowned for its power and versatility. In this ultimate guide, we will explore how to achieve over 700 rear-wheel horsepower (RWHP) using a TrickFlow top-end setup and boosted support. Whether you are a seasoned builder or a novice enthusiast, this guide will provide you with the essential steps and considerations for a successful LS swap.

Understanding the LS Engine

The LS engine family, introduced in 1997, has revolutionized the performance landscape. With its lightweight aluminum construction and efficient design, it offers a solid foundation for high horsepower builds. Key features include:

  • V8 configuration with a compact design
  • Interchangeable components across various LS generations
  • Robust aftermarket support for performance upgrades

Choosing the Right LS Engine

When selecting an LS engine for your swap, consider the following factors:

  • Displacement: Common choices include the LS1, LS2, LS3, and LS6, with varying power outputs.
  • Block Material: Aluminum blocks are lighter, while iron blocks offer increased durability.
  • Intended Use: Determine whether your build is for street use, racing, or a combination of both.

Essential Components for Your LS Swap

To achieve 700+ RWHP, certain components are essential for your LS swap. Here’s a list of key parts you will need:

  • Engine Management System: A quality ECU is crucial for tuning and performance.
  • Fuel System: Upgraded injectors and a high-flow fuel pump will support increased power demands.
  • Exhaust System: A performance exhaust will improve airflow and enhance sound.
  • Cooling System: An upgraded radiator and intercooler are necessary for managing heat.
  • Transmission: Ensure your transmission can handle the power; consider a performance automatic or manual.

Installing the TrickFlow Top-End Kit

The TrickFlow top-end kit is a popular choice for maximizing airflow and power. Follow these steps for installation:

  • Remove the Stock Intake and Heads: Begin by disassembling the existing components.
  • Install TrickFlow Cylinder Heads: Follow the manufacturer’s instructions for proper torque specifications.
  • Install the Intake Manifold: Ensure a proper seal with gaskets and bolts.
  • Upgrade the Camshaft: Consider a camshaft that complements your intended power goals.

Boosting Power with Forced Induction

To achieve the coveted 700+ RWHP, adding forced induction is essential. Here are common options:

  • Supercharger: Offers instant power and torque across the RPM range.
  • Turbocharger: Provides higher peak power and efficiency at higher RPMs.

Tuning for Maximum Performance

Once your engine is assembled and installed, tuning is critical. Here’s how to approach it:

  • Dyno Tuning: Utilize a professional dyno tuner to optimize fuel maps and ignition timing.
  • Monitor A/F Ratios: Ensure the air-fuel mixture is within optimal ranges for performance and safety.
  • Adjust for Boost: If using forced induction, be mindful of boost levels and detonation risks.

Final Considerations

Achieving 700+ RWHP with a Chevy LS swap requires careful planning and execution. Here are final tips to ensure success:

  • Budget Wisely: Performance parts can add up; plan your budget accordingly.
  • Research Thoroughly: Stay informed about the latest components and techniques in the LS community.
  • Join Forums and Groups: Engage with other LS enthusiasts for advice and support.

With the right setup and attention to detail, your LS swap can yield impressive power and performance. Enjoy the journey of building your ultimate Chevy LS project!
