The camshaft controls the timing and duration of valve openings, which directly affects engine power and efficiency. It’s essential to understand what a cam kit entails, which usually includes the camshaft itself, lifters, and sometimes, springs and other necessary components. Types of Camshafts There are several types of camshafts to consider. I found it helpful to categorize them based on my performance goals. Hydraulic flat tappet cams are great for street performance, while roller cams offer better efficiency and higher RPM potential. Choosing the right type is crucial for achieving the performance I desire from my small block Chevy. Performance Needs Determining my performance needs was a vital step in the buying process. I had to consider how I plan to use my vehicle. If I’m building a street car, I want a cam that provides good low-end torque and smooth drivability. For a track-focused build, I would prioritize higher RPM power and aggressive profiles. Knowing my intended use helped narrow down my options significantly. Specifications to Consider As I explored different cam kits, I paid close attention to specifications like lift, duration, and lobe separation angle. Lift affects how much air and fuel enters the engine, while duration influences when the valves open and close. The lobe separation angle helps determine the cam’s character and how it interacts with engine components. Understanding these specs allowed me to make informed decisions tailored to my setup. Compatibility with Engine Components I learned that compatibility is key when selecting a cam kit. It’s essential to ensure that the camshaft works well with my existing engine components, like the intake manifold, cylinder heads, and exhaust system. I always double-checked the specifications of my engine to avoid potential mismatches that could lead to performance issues. Installation Considerations Installation can be a daunting task, but I found it manageable with the right tools and knowledge. I had to consider whether I wanted to tackle the installation myself or hire a professional. If I chose to do it myself, I ensured I had all necessary tools and followed a detailed guide. Hiring a professional might be the best option if I felt uncertain about any aspect of the installation process. Budgeting for Cam Kits Setting a budget was one of the most critical steps in my buying journey. I discovered that cam kits can vary widely in price, depending on the brand, type, and included components. I had to balance my performance goals with my budget. I found it helpful to look for kits that offered the best value rather than simply the cheapest option. Researching Brands and Reviews Before making my final decision, I researched various brands and read reviews from other small block Chevy enthusiasts. I found forums and online communities to be invaluable resources. Hearing about the experiences of others helped me gauge reliability and performance, giving me confidence in my choice.
