Practical Buying Advice:

Choosing the best performance camshaft for your Chevy 350 depends heavily on your goals. Consider your budget, intended use (street, strip, off-road), and the overall condition of your engine. Don’t underestimate the importance of supporting modifications. A more aggressive cam may require upgrades to your valve springs, pistons, heads, and even your intake manifold and carburetor or fuel injection system to perform optimally. Research carefully and consult with experienced engine builders if you’re unsure.

Final Verdict:

There’s no single “best” camshaft. The ideal choice hinges on your priorities. For a balance of power and drivability, the Comp Cams options present compelling choices. If peak horsepower is paramount, even with supporting modifications needed, consider the high-lift options (with caution!). Remember, proper installation and potential tuning are essential for optimal performance and engine health.

FAQ:

Q: What are the key factors to consider when choosing a camshaft for my Chevy 350?
A: Key factors include your budget, desired performance level (street, strip, etc.), engine modifications, and driving style. Consider the cam’s lift, duration, lobe separation angle, and whether it’s hydraulic or solid lifter.

Q: Will I need other engine modifications when installing a performance camshaft?
A: Often, yes. More aggressive cams may necessitate upgraded valve springs, pushrods, and possibly even heads and pistons.

Q: What is the difference between a hydraulic and a solid lifter camshaft?
A: Hydraulic lifters automatically adjust valve lash, requiring less maintenance. Solid lifters require manual adjustment but can often provide better performance at high RPM.

Q: How much horsepower can I expect to gain with a performance camshaft?
A: Gains vary significantly based on the cam, engine build, and other modifications. You can expect anywhere from a modest increase to a substantial jump in horsepower.

Q: Is it difficult to install a performance camshaft?
A: While not a simple task, many camshaft installations are manageable for experienced DIY mechanics. Refer to detailed instructions for your specific cam. If you lack experience, consider professional installation.

Q: What kind of best performance camshafts for Chevy 350 engines should I choose for a daily driver?
A: For a daily driver, prioritize a camshaft with a relatively mild profile that balances performance with good street manners and a reasonable idle quality. Avoid extremely aggressive cams unless you’re prepared for a very noticeable lope at idle and potentially reduced low-end torque.
