Buying Guide: Choosing the Right Camshaft for Chevy 350 Engines
Camshaft Types
- Flat Tappet Camshafts – Traditional design, less costly but may require proper break-in and specific oil formulations.
- Hydraulic Roller Camshafts – Offer improved performance and durability, reduce friction and wear, often preferred for modern builds.
- Solid Roller Camshafts – Used mostly in racing applications; require more maintenance and tuning.
Engine Application
- Street Performance: Choose cams that provide a balance between power and smooth idle to ensure drivability.
- Race/Off-Road: Opt for aggressive cams with higher duration and lift, favoring maximum power at high RPMs.
- Towing/Heavy Duty: Look for cams enhancing low-to-mid range torque for better pulling power and response.
- Marine Uses: Ensure that the camshaft is compatible with marine conditions, balance shafts, and corrosion resistance.
Compatibility & Fitment
- Confirm engine years and model size compatibility (e.g., 350 SBC from 1967-2003).
- Ensure proper lifter type compatibility (hydraulic flat tappet vs. hydraulic roller lifters).
- Consider the valvetrain components like rocker arms, pushrods, and springs needed with the camshaft choice.
Performance Characteristics
- Duration: Longer durations increase power at high RPM but can reduce low-end torque.
- Lift: Higher lift improves airflow but may require upgraded valve springs.
- Lobe Separation Angle (LSA): Affects idle quality and power curve; narrower LSA often yields more valve overlap and power.
- Operating RPM Range: Match the cam’s RPM range to your typical driving style or usage.
Additional Tips
- Check for manufacturer recommendations regarding stall speed of the torque converter if applicable.
- Consult vehicle gear ratios to ensure camshaft performance complements drivetrain setup.
- When upgrading camshafts, review or upgrade related parts such as timing chains, lifters, and valve springs.
- Consider professional tuning after installation to maximize performance gains and engine reliability.
