Buying Guide for the Best Camshaft For 350 Chevy
Choosing the right camshaft for your 350 Chevy engine is crucial for optimizing performance and ensuring your vehicle runs smoothly. The camshaft is a key component in the engine's valve train, controlling the timing and duration of the opening and closing of the valves. This directly affects the engine's power, efficiency, and overall performance. When selecting a camshaft, it's important to consider your vehicle's intended use, whether it's for daily driving, racing, or towing. Understanding the key specifications will help you make an informed decision that best suits your needs.LiftLift refers to how far the camshaft opens the valves. Higher lift can increase the amount of air and fuel mixture entering the engine, which can boost power. However, too much lift can cause wear and tear on the valve train components. For street performance, a moderate lift is usually sufficient, while racing applications may benefit from higher lift values.
DurationDuration is the amount of time the valve stays open, measured in degrees of crankshaft rotation. Longer duration can improve high-RPM power but may reduce low-end torque and idle quality. For daily driving, a shorter duration is typically preferred for better drivability and fuel efficiency. For racing, a longer duration can help achieve higher performance at the expense of low-end power.
Lobe Separation Angle (LSA)Lobe Separation Angle (LSA) is the angle between the intake and exhaust lobes on the camshaft. A wider LSA can improve idle quality and vacuum, making it suitable for street use. A narrower LSA can increase overlap, which can enhance high-RPM performance but may result in a rougher idle. Choose an LSA based on whether you prioritize smooth operation or maximum performance.
RPM RangeThe RPM range indicates the engine speeds at which the camshaft performs best. Camshafts designed for low to mid-range RPMs are ideal for street driving and towing, providing good low-end torque and drivability. High RPM camshafts are better suited for racing, where maximum power at high engine speeds is desired. Match the camshaft's RPM range to your driving style and vehicle use.
Valve TimingValve timing refers to the timing of the opening and closing of the valves in relation to the position of the piston. Proper valve timing ensures optimal engine performance and efficiency. Adjustable timing can allow for fine-tuning to match specific performance goals. Consider a camshaft with adjustable timing if you plan to make precise adjustments for racing or high-performance applications.
