Buying Guide for Performance Cams for Chevy 350
When choosing a performance camshaft for your Chevy 350 engine, consider the following key factors:
- Intended Use: Determine whether the cam is for street, towing, off-road, or racing use. Different cams optimize either low-end torque or high-end horsepower.
- Cam Type: Decide between hydraulic flat tappet cams and hydraulic roller cams. Roller cams tend to offer better durability and more aggressive profiles but may require compatible components like roller lifters.
- Valve Lift and Duration: Higher lift and longer duration generally increase power but can affect idle quality and emissions. Balance performance goals with drivability.
- Lobe Separation Angle (LSA): A narrower LSA can increase power but may cause a rougher idle and less vacuum. A wider LSA improves idle but reduces overlap, affecting power delivery.
- RPM Range: Select a cam that matches your engine’s operating speed for optimal performance. High-stall converters and gear ratios may be necessary for aggressive cams.
- Compatibility: Verify cam compatibility with your engine year and configuration, including any necessary supporting parts such as lifters and timing sets.
- Engine Management: Some cams require tuning or computer calibration to optimize air/fuel and ignition timing for smooth operation and maximum gains.
Considering these elements will help you select a camshaft that enhances your Chevy 350’s performance while maintaining reliability and drivability suitable for your needs.
