by

The Chevy S-10 has long been a favorite among truck enthusiasts for its compact size and versatility. However, many owners yearn for more power and performance. One of the most popular upgrades is the V8 swap, particularly using a junkyard LS engine. This article details how I transformed my S-10 with a $2,000 LS engine, significantly boosting its power and performance.

Why Choose an LS Engine?

The LS engine family, originally produced by General Motors, is known for its performance, reliability, and aftermarket support. Here are some reasons why it’s an excellent choice for a V8 swap:

  • Powerful Performance: LS engines produce significant horsepower and torque compared to the stock S-10 engines.
  • Lightweight: The aluminum construction of many LS engines helps reduce weight, improving handling and performance.
  • Aftermarket Support: A vast array of parts and support is available, making upgrades and repairs easier.
  • Cost-Effective: Junkyard LS engines can often be found for a fraction of the cost of new engines.

Finding the Right LS Engine

Before starting the swap, I needed to find a suitable LS engine. Here’s how I went about it:

  • Research Local Junkyards: I spent time researching local junkyards that specialize in GM vehicles.
  • Inspect Engines: I visited several yards and inspected the engines for signs of wear or damage.
  • Check for Compatibility: I made sure to select an engine that would fit my S-10 without extensive modifications.
  • Negotiate Price: I was able to negotiate the price down to $2,000, which included the engine and some accessories.

Preparing for the Swap

Once I had the LS engine, it was time to prepare my S-10 for the swap. Here’s what I did:

  • Gather Tools: I made sure I had all necessary tools, including wrenches, sockets, and an engine hoist.
  • Remove the Old Engine: I carefully removed the stock engine, taking note of how everything was connected.
  • Clean the Engine Bay: I took the opportunity to clean the engine bay, removing any debris and rust.
  • Plan for Wiring: I researched the wiring harness needed for the LS engine to ensure compatibility.

Executing the Swap

With everything prepared, it was time to install the LS engine. The process involved several key steps:

  • Install Engine Mounts: I used aftermarket engine mounts designed for the S-10 to ensure a proper fit.
  • Hoist the Engine: With the help of a friend, I carefully hoisted the LS engine into place.
  • Connect Transmission: I mated the LS engine to the existing transmission, ensuring a secure connection.
  • Wiring and Plumbing: I connected the wiring harness and ensured all plumbing was correctly routed.

Tuning and Testing

After the installation, tuning was essential to maximize performance. Here’s how I approached it:

  • Initial Start-Up: I performed an initial start-up to check for leaks and ensure everything was functioning properly.
  • Professional Tuning: I took the truck to a professional tuner to optimize the engine’s performance.
  • Test Drive: After tuning, I went for a test drive to experience the power boost firsthand.

Performance Improvements

The results of the LS swap were remarkable. Here’s what I noticed:

  • Increased Horsepower: The truck now boasted significantly more horsepower, making acceleration exhilarating.
  • Improved Torque: The added torque made towing and hauling much easier.
  • Better Fuel Efficiency: Surprisingly, the LS engine provided better fuel efficiency than the stock engine.

Conclusion

The LS engine swap transformed my Chevy S-10 into a powerful machine. For anyone considering a similar upgrade, I highly recommend researching thoroughly, planning carefully, and enjoying the process. With the right approach, you can achieve significant performance gains without breaking the bank.
