What Specifications Should You Consider for the Best RV Cam for SBC 350?

When selecting the best RV cam for an SBC 350, several key specifications should be taken into account to ensure optimal performance and compatibility.

• Duration: The duration of the camshaft indicates how long the valves stay open, measured in degrees of crankshaft rotation. A longer duration can enhance power at higher RPMs, which is beneficial for RVs that require more torque for towing, while a shorter duration can improve low-end torque and drivability.
• Lift: Lift refers to how far the valves are opened by the camshaft. Higher lift can lead to increased airflow into the engine, resulting in better performance. However, it’s important to ensure that the rest of the engine components, such as the springs and pistons, can accommodate the increased lift without causing damage.
• LSA (Lobe Separation Angle): The LSA is the angle between the intake and exhaust lobes of the camshaft. A wider LSA typically provides better idle characteristics and smoother operation, which is crucial for RVs that need to maintain a comfortable driving experience. Conversely, a narrower LSA can enhance performance at higher RPMs but may compromise drivability.
• Type of Cam: There are different types of camshafts, including hydraulic flat tappet, hydraulic roller, and solid types. Hydraulic roller cams are often preferred for RV applications due to their better performance and longevity, while flat tappet cams can be more budget-friendly but may require more maintenance.
• RPM Range: The RPM range indicates the optimal operating range for the camshaft. An RV cam should be designed to perform well in the engine’s typical RPM range, which is generally lower than performance-oriented applications. Ensuring the cam matches the intended use of the vehicle is essential for achieving the desired power and torque.
• Compatibility with Exhaust and Intake: The camshaft should work well with the existing exhaust and intake systems of the SBC 350. Upgrading the cam without considering these components can lead to suboptimal performance, as the entire airflow system needs to be balanced to maximize efficiency and power delivery.

How Does Cam A Enhance Performance for SBC 350?

The best RV cams for SBC 350 enhance engine performance by optimizing power, torque, and efficiency tailored for recreational vehicles.

• Increased Lift: A cam with higher lift allows the engine to draw in more air and fuel, which can significantly improve horsepower and torque. This is particularly beneficial in an RV application where power is needed for acceleration and towing capabilities.
• Longer Duration: A cam with extended duration keeps the intake and exhaust valves open longer, allowing for more complete combustion. This results in better fuel efficiency and overall performance, making it ideal for long-distance travel in an RV.
• Improved Overlap: Overlap refers to the period when both the intake and exhaust valves are open simultaneously. A cam with optimized overlap can improve engine breathing at higher RPMs, which is advantageous for maintaining speed on highways while minimizing engine strain.
• Optimal Lobe Separation Angle: The lobe separation angle affects how the camshaft controls valve timing. A cam with the right angle can enhance both torque and horsepower in the desired RPM range, which is crucial for the varied driving conditions RVs often encounter.
• Compatibility with RV Accessories: Many RV cams are designed to work seamlessly with other engine modifications, such as headers and performance exhaust systems. This compatibility ensures that all components work together efficiently, providing a boost in overall engine performance.
