The 5.7 HEMI engine has gained a reputation for its power and performance, making it a popular choice among automotive enthusiasts. One of the key factors that influence the engine’s performance is the camshaft profile. In this article, we will compare cam profiles from three leading manufacturers: COMP Cams, Lunati, and Ferrea. We will analyze how these cam profiles impact both power and driveability, helping you make an informed decision for your build.
Understanding Camshaft Profiles
A camshaft controls the timing and duration of the engine’s valve openings and closings. The profile of a camshaft can significantly affect engine performance characteristics. Key aspects of cam profiles include:
- Lift: The distance the valve is opened.
- Duration: The length of time the valve remains open.
- Overlap: The period when both intake and exhaust valves are open.
These factors contribute to how the engine breathes, its power band, and overall driveability. A well-chosen cam profile can enhance performance while maintaining a smooth driving experience.
