Factors that determine the best camshaft:
* Current Engine Setup: What are your engine's current specs? This includes:
* Compression Ratio: Higher compression will benefit from a more aggressive cam.
* Heads: Are they stock or aftermarket? This influences flow and the camshaft's compatibility.
* Intake and Exhaust Manifolds: The type of manifolds will affect exhaust flow and the cam's suitability.
* Transmission: Automatic or manual? This determines the ideal stall converter or clutch setup.
* Desired Performance: Are you looking for:
* Increased Power: A cam with more lift and duration will provide more power, but might sacrifice low-end torque.
* Improved Fuel Economy: A mild cam might improve fuel economy, especially at cruising speeds.
* Smooth Idle: A cam with less duration and lift will provide a smoother idle but might limit power.
* Torque: A cam with a shorter duration and more lift can improve low-end torque.
* Driving Style: How do you plan to use the truck?
* Daily driver?
* Off-roading?
* Towing?
Cam Selection Process:
1. Research: Find reputable camshaft manufacturers (e.g., Comp Cams, Crane Cams, Lunati).
2. Use Cam Selection Tools: Most manufacturers have online tools that help you choose a cam based on your engine specs and desired performance.
3. Consult Experts: Talk to a local engine builder or performance shop for advice and recommendations.
General Tips:
* Start with a mild cam: A mild cam provides a good balance of power and drivability.
* Consider the cam's operating range: Choose a cam that matches your desired RPM range.
* Adjust valve springs: If you're installing a more aggressive cam, you'll likely need to upgrade your valve springs.
Remember: Upgrading your camshaft can significantly impact your engine's performance. It's crucial to choose the right cam for your specific needs and to have it properly installed.
