The Tri-Five Chevrolets, produced between 1955 and 1957, have become iconic in the automotive world. Known for their classic design and powerful performance, many enthusiasts are looking to enhance their capabilities. In this article, I will share my experience with a $2,500 Summit Racing build that significantly transformed my Tri-Five’s performance.
The Starting Point
Before diving into the build, it’s important to understand the starting point of my vehicle. My 1956 Chevrolet Bel Air was equipped with a stock 265 cubic inch V8 engine, producing around 162 horsepower. While it was a classic beauty, the performance left much to be desired, especially when compared to modern vehicles.
Setting a Budget
With a budget of $2,500, my goal was to maximize performance without compromising the classic feel of the car. I decided to focus on key components that would enhance power and drivability. This budget included parts from Summit Racing, which is known for its quality aftermarket components.
The Build Components
Here’s a breakdown of the main components I selected for the build:
- Intake Manifold: I opted for a dual-plane intake manifold to improve airflow.
- Carburetor: A Holley 600 CFM carburetor was chosen for better fuel delivery.
- Headers: I installed long-tube headers to enhance exhaust flow.
- Camshaft: A mild performance camshaft was added for increased power without sacrificing reliability.
- Ignition System: Upgrading to an electronic ignition system improved spark efficiency.
Installation Process
The installation process was a mix of excitement and challenges. With some mechanical knowledge, I tackled most of the work myself, but I also sought help from friends who were more experienced with engine builds.
Intake and Carburetor Installation
Installing the new intake manifold and carburetor was straightforward. I carefully followed the instructions, ensuring all gaskets were in place to prevent leaks. The improvement in throttle response was noticeable right away.
Headers and Exhaust
Replacing the stock exhaust manifolds with long-tube headers required some finesse. I had to maneuver around various components, but the resulting sound and performance boost made it worthwhile.
Camshaft and Ignition Upgrade
Swapping the camshaft was the most intensive part of the build. It required removing the timing cover and carefully aligning everything. The electronic ignition upgrade was a simple swap and significantly improved engine response.
The Results
After completing the build, I took my Tri-Five for a test drive. The difference in performance was astounding. The engine felt more alive, with a noticeable increase in power and torque. Here are some key improvements I experienced:
- Horsepower: The estimated horsepower jumped to around 250.
- Torque: Torque improved significantly, making acceleration smoother.
- Throttle Response: The engine responded instantly to the gas pedal.
- Sound: The new exhaust setup produced a deep, aggressive tone.
Conclusion
My $2,500 Summit Racing build transformed my Tri-Five from a classic cruiser into a powerful performer. The enhancements not only improved performance but also made driving the car a more enjoyable experience. For anyone considering a similar upgrade, I highly recommend focusing on key components that provide the most impact within your budget.
With careful planning and execution, you can achieve remarkable results while preserving the classic charm of your vehicle. Happy building!
