The Chevrolet Camaro has long been a symbol of American muscle, and upgrading its engine components can unlock even more power and performance. One of the most significant improvements you can make to a Camaro 350 small block is upgrading the camshaft and pistons. This article will explore how these modifications can help you achieve over 450 horsepower and enhance throttle response.
Understanding the Camaro 350 Small Block
The Camaro 350 small block is a classic engine known for its versatility and performance potential. With a displacement of 350 cubic inches, this engine is a favorite among car enthusiasts. However, to truly unleash its power, certain upgrades are necessary.
The Importance of Camshaft Upgrades
The camshaft plays a crucial role in determining the engine’s performance characteristics. It controls the timing and duration of the valve openings, which directly affects airflow and power output. Upgrading the camshaft can lead to significant gains in horsepower and torque.
Choosing the Right Camshaft
When selecting a camshaft for your Camaro 350 small block, consider the following factors:
- Lift and Duration: Higher lift and longer duration can improve airflow, but may require additional modifications.
- RPM Range: Choose a camshaft that matches your desired power band. Street-friendly cams typically have a lower RPM range.
- Type of Driving: Consider whether you will be using your Camaro for daily driving, racing, or a mix of both.
Popular Camshaft Options
Some popular camshaft options for the Camaro 350 small block include:
- Comp Cams Xtreme Energy: Known for its aggressive profile and excellent throttle response.
- Summit Racing Camshaft: A great budget option that still offers impressive performance gains.
- Edelbrock Performer RPM: Ideal for those looking for a balance between street and performance driving.
Enhancing Performance with Pistons
In addition to the camshaft, upgrading the pistons is essential for maximizing horsepower. The right pistons can improve compression and overall engine efficiency.
Benefits of Upgrading Pistons
Upgrading to high-performance pistons offers several advantages:
- Increased Compression: Higher compression ratios lead to more power and better combustion efficiency.
- Lightweight Materials: Forged pistons are lighter, reducing overall engine weight and improving throttle response.
- Durability: High-performance pistons are designed to withstand higher temperatures and pressures.
Choosing the Right Pistons
When selecting pistons for your Camaro 350 small block, keep these factors in mind:
- Material: Forged pistons are recommended for high-performance applications due to their strength.
- Compression Ratio: Determine the ideal compression ratio based on your camshaft and fuel type.
- Fitment: Ensure the pistons are compatible with your engine block and other components.
Combining Camshaft and Pistons for Maximum Power
To achieve over 450 horsepower, it’s crucial to combine the right camshaft and piston upgrades. The synergy between these components can lead to significant performance improvements.
Tuning and Supporting Modifications
After upgrading the camshaft and pistons, consider the following supporting modifications:
- Upgraded Intake and Exhaust: Improve airflow with a high-performance intake manifold and exhaust system.
- ECU Tuning: Proper tuning is essential to optimize fuel delivery and ignition timing.
- High-Performance Fuel System: Ensure adequate fuel flow with upgraded injectors and fuel pumps.
Conclusion
Upgrading the camshaft and pistons in your Camaro 350 small block can unlock impressive power and enhance throttle response. By carefully selecting the right components and considering supporting modifications, you can achieve over 450 horsepower and take your driving experience to the next level.
