When I first acquired my classic Camaro, it was a dream come true. However, the stock engine left much to be desired in terms of power and performance. With only 250 horsepower, the driving experience was not as exhilarating as I had hoped. After much research and consideration, I decided to upgrade to a crate GM 350 HO engine, which promised to boost my Camaro’s output to around 350 horsepower. This article will detail my journey through the build process and the transformation it brought to my beloved vehicle.
Choosing the Right Engine
The first step in my journey was selecting the right engine. The GM 350 HO crate engine stood out due to its reputation for reliability and performance. Here are some of the factors that influenced my decision:
- Power Output: The 350 HO engine delivers 350 horsepower, a significant increase over the stock engine.
- Torque: With 400 lb-ft of torque, the engine offers impressive acceleration.
- Compatibility: Designed for classic vehicles, the engine fits well within the Camaro’s engine bay.
- Reputation: GM’s crate engines are known for their quality and performance.
The Build Process
Once I decided on the crate GM 350 HO engine, it was time to start the build process. Here are the key steps I took to ensure a successful installation:
- Preparation: I gathered all necessary tools and components, including the engine, wiring harness, and engine mounts.
- Removal of the Old Engine: Carefully disconnected and removed the stock engine, taking care to label all wires and hoses for easy reinstallation.
- Engine Bay Cleaning: Cleaned the engine bay thoroughly to remove any dirt and debris, ensuring a clean environment for the new engine.

- Wiring and Connections: Reconnected all electrical components, ensuring proper alignment with the new engine’s wiring harness.
- Final Checks: Conducted a thorough inspection to ensure everything was in place before starting the engine.
Performance Improvements
After completing the installation, it was time to take the Camaro for a test drive. The difference in performance was immediately noticeable. Here are some of the key improvements I experienced:
- Acceleration: The Camaro now accelerates with authority, making merging onto highways and overtaking other vehicles a breeze.
- Throttle Response: The engine provides a much more responsive throttle, allowing for quicker reactions when needed.
- Sound: The new engine emits a powerful and aggressive sound that truly enhances the driving experience.
- Fuel Efficiency: Surprisingly, the fuel efficiency remained reasonable, especially considering the power increase.
Challenges Faced
While the build process was largely successful, I did encounter some challenges along the way. Here are a few hurdles I faced:
- Fitment Issues: Initially, I had some trouble fitting the new engine due to minor discrepancies in the engine mounts.
- Wiring Complications: The wiring harness was not a perfect match, requiring some modifications to connect everything properly.
- Cooling System Upgrade: I needed to upgrade the radiator to handle the increased heat generated by the new engine.
Final Thoughts
The transformation of my classic Camaro from 250 to 350 horsepower has been nothing short of exhilarating. The crate GM 350 HO engine has breathed new life into the vehicle, making it a joy to drive.
