What Is the Function of a Blower Cam in a 350 Chevy?
The function of a blower cam in a 350 Chevy is crucial for optimizing engine performance, especially when paired with a supercharger or blower. The primary role of the blower cam is to enhance airflow and fuel delivery during both the intake and exhaust strokes, ensuring that the engine can handle the increased pressure created by the forced induction system.
Key aspects of a blower cam include:
-
Increased Lift and Duration: A blower cam typically has greater lift and duration than a standard camshaft. This design allows for more air and fuel to enter the combustion chamber, maximizing power output.
-
Adjustable Timing: Many blower cams offer adjustable timing options, which enable enthusiasts to tailor the camshaft’s profile to match the specific supercharger setup, providing optimal performance for various RPM ranges.
-
Improved Cylinder Pressure: By optimizing the valve timing and lift, a blower cam increases the cylinder pressure, leading to better combustion efficiency and increased horsepower.
-
Throttle Response: A properly selected blower cam enhances throttle response, which is particularly beneficial during acceleration and while navigating varied driving conditions.
Selecting the right blower cam for a 350 Chevy ensures that the engine operates efficiently, producing maximum power and torque while maintaining reliability under higher boost levels.
What Key Features Should You Consider When Choosing a Blower Cam for a 350 Chevy?
When choosing a blower cam for a 350 Chevy, several key features should be considered to ensure optimal performance and compatibility.
- Lift: The lift of a camshaft refers to how far the valve opens, which affects airflow into the engine. For a blower setup, a higher lift can enhance performance by allowing more air and fuel to enter the combustion chamber, but it must be balanced with the duration to avoid sacrificing low-end torque.
- Duration: Duration is the amount of time the valve remains open during the engine cycle, measured in degrees of crankshaft rotation. A blower cam typically has a longer duration to accommodate the increased airflow from the supercharger, which helps to maximize power output at higher RPMs.
- Lobe Separation Angle (LSA): The LSA determines the angle between the intake and exhaust lobes and influences engine vacuum and idle quality. A wider LSA can improve drivability and reduce overlap, which is beneficial for forced induction applications like a blower, ensuring smoother operation and better performance across the RPM range.
- Material and Design: The camshaft’s material and design will affect durability and performance. Consider using a forged steel cam for strength and longevity, especially in high-performance applications where your engine will face increased stress from the blower.
- Compatibility with Supercharger: It’s crucial to ensure that the camshaft is specifically designed to work with a supercharger setup. A cam that complements the boost characteristics of the supercharger can enhance overall performance, while one that doesn’t may lead to inefficient operation or potential engine damage.
- Idle Characteristics: The idle quality of the engine with a blower cam is important for daily drivability. A cam with a more aggressive profile can produce a rougher idle, which might be undesirable for some drivers, so considering how the cam affects idle should align with your driving preferences.

What Steps Should Be Followed to Properly Install a Blower Cam in a 350 Chevy?
To properly install a blower cam in a 350 Chevy, follow these essential steps:
- Gather Necessary Tools and Materials: Before starting the installation, ensure you have all the required tools and components, including the blower cam, camshaft installation tool, timing chain, and any gaskets or seals needed for reassembly.
- Prepare the Engine: Disconnect the battery, drain the coolant, and remove any components obstructing access to the engine, such as the intake manifold, valve covers, and timing cover.
- Remove the Old Camshaft: Use a camshaft removal tool to carefully extract the existing camshaft from the engine. Take note of the timing marks and ensure that the engine is at top dead center (TDC) before proceeding.
- Install the New Blower Cam: Align the new blower cam with the timing chain and slide it into place, ensuring it fits snugly and the timing marks align correctly for optimal performance.
- Reassemble Engine Components: Replace the timing chain, install new gaskets, and reattach all components that were removed earlier, including the valve covers and intake manifold, ensuring a proper seal to prevent leaks.
- Adjust Timing and Valves: After reassembly, adjust the ignition timing and valve settings according to the specifications for the new blower cam to achieve the best performance and efficiency.
- Test the Installation: Reconnect the battery, refill the coolant, and start the engine to check for any unusual noises or leaks, allowing the engine to reach operating temperature while monitoring its performance.
What Common Mistakes Can You Avoid When Selecting a Blower Cam for a 350 Chevy?
When selecting a blower cam for a 350 Chevy, avoiding common mistakes can significantly enhance performance and reliability.
- Choosing the Wrong Lift: It’s crucial to select a cam with the appropriate lift for your engine setup. A cam with too much lift can cause valve clearance issues, while too little lift may not allow the engine to breathe adequately, limiting performance.
- Ignoring Duration Specifications: The duration of the cam affects how long the valves remain open. A cam with too long a duration can lead to a loss in low-end torque, while one that is too short may not take full advantage of the blower’s capabilities, impacting overall power delivery.
- Not Considering Lobe Separation Angle: The lobe separation angle (LSA) can influence the engine’s power band and idle characteristics. A narrow LSA can increase overlap, which may enhance high RPM performance but could compromise idle quality and lower RPM torque.
- Overlooking the Engine’s Compression Ratio: The compression ratio of your engine should match the cam profile you select. A cam that is too aggressive for a lower compression engine can lead to detonation issues, while a milder cam may not fully utilize the potential of a high-compression setup.
- Failing to Match with Other Components: It’s essential to ensure that the cam matches other components like the intake, exhaust, and ignition system. Mismatched components can lead to poor performance and drivability issues, negating the benefits of a well-chosen cam.
- Neglecting to Check for Compatibility with Boost: When using a blower, it’s important to select a cam that can handle the increased air flow and pressure. Not all cams are designed for forced induction, and using an incompatible cam can result in engine damage or reduced performance.
