The Camaro 350 small block is a classic engine known for its performance and versatility. Upgrading the cam and valvetrain can significantly enhance its power and RPM capabilities. This article will guide you through the necessary steps and considerations for achieving higher RPM and power gains in your Camaro 350 small block.
Understanding the Basics of Camshafts
A camshaft is a crucial component that controls the timing and duration of the engine’s valve openings. The right camshaft can optimize engine performance by improving airflow and increasing RPM. When selecting a camshaft for your Camaro 350, consider the following:
- Lift: The height the valve is lifted off its seat.
- Duration: The time the valve stays open during the crankshaft rotation.
- Overlap: The period when both the intake and exhaust valves are open.
Selecting the Right Camshaft
Choosing the right camshaft depends on your performance goals and the type of driving you plan to do. Here are some considerations:
- Street vs. Race: A street cam provides better drivability, while a race cam maximizes power at higher RPMs.
- Engine Specs: Consider your engine’s compression ratio and intended RPM range.
- Support Components: Ensure that your valvetrain components can handle the new camshaft specifications.
Upgrading the Valvetrain Components
In addition to the camshaft, upgrading the valvetrain components is essential for maximizing performance. Key components to consider include:
- Valve Springs: High-performance valve springs prevent valve float at higher RPMs.
- Pushrods: Upgraded pushrods ensure proper alignment and strength.
- Rockers: Adjustable or roller rockers can improve efficiency and power delivery.
Installation Process
Installing a new camshaft and valvetrain requires careful attention to detail. Follow these steps for a successful installation:
- Preparation: Gather all necessary tools and components before starting.
- Remove the Old Cam: Follow the manufacturer’s instructions to safely remove the old camshaft.
- Install New Components: Carefully install the new camshaft and valvetrain components, ensuring proper alignment.
- Reassemble: Reassemble the engine, double-checking all connections and torque specifications.
Tuning for Optimal Performance
After installation, tuning your Camaro 350 is crucial to achieving the best performance. Here are some tuning considerations:
- ECU Tuning: Adjust the engine control unit for optimal fuel and timing settings.
- Dyno Testing: Consider a dyno session to measure power gains and make necessary adjustments.
- Fuel Quality: Use high-octane fuel to maximize performance and prevent knocking.
Benefits of Upgrading the Cam and Valvetrain
Upgrading the cam and valvetrain of your Camaro 350 small block can lead to numerous benefits, including:
- Increased Horsepower: Improved airflow and timing result in higher horsepower output.
- Higher RPM Capability: A performance cam allows the engine to rev higher, enhancing acceleration.
- Better Throttle Response: Upgraded components provide a more responsive driving experience.
Conclusion
Upgrading the cam and valvetrain of your Camaro 350 small block is an effective way to achieve significant power gains and higher RPM capabilities. By selecting the right components and following proper installation and tuning procedures, you can unlock the full potential of your engine. Whether for street performance or racing, these upgrades will enhance your driving experience.
