it's essential to understand the basic terminology associated with camshafts. Terms like lift, duration, lobe separation angle (LSA), and overlap are critical in determining a camshaft's performance characteristics.
Lift:
Refers to how much the camshaft opens the valves. It's usually measured in inches or millimetres.
Duration:
Represents how long the valves stay open during each cycle. Duration is measured in degrees of crankshaft rotation.
Lobe Separation Angle (LSA):
The angle between the centrelines of the intake and exhaust lobes on the camshaft. It affects the engine's idle quality, vacuum, and power characteristics.
Overlap:
The period when both the intake and exhaust valves are open. Overlap influences exhaust scavenging and can impact performance.
Now we have the basics covered. Lets ask ourselves some questions in order to choose the correct cam shaft. The aim here is to figure out exactly how you plan on using the car what your expectations and power goals are and what modifications if any have already been done or what you plan on doing in the future.
Vehicle Use and Driving Conditions:
Consider the primary use of your vehicle. Is it a daily driver, a weekend only car, or something built for track or high performance applications? You should also match the camshaft's specifications to your driving conditions. A camshaft optimized for street driving may not be suitable for a dedicated track car and vice versa.
Power Goals:
Define your power goals. Whether you're looking for low-end torque, high-end horsepower, or a balanced combination for daily driving, your camshaft choice plays a significant role on how the car performance and drives day to day.
Compression Ratio:
Ensure compatibility with your engine's compression ratio. Camshafts designed for high compression engines may not perform optimally in low compression setups or for engines that have been built for turbo applications.
Transmission Type:
Consider your vehicle's transmission type. Automatic and manual transmissions require different camshaft profiles to optimize performance.
Camshaft Type:
Hydraulic or solid? Roller or flat tappet? Each camshaft type has its advantages and disadvantages, so choose based on your preferences, maintenance considerations, and budget.

Installation and Tuning
Once you've selected the right camshaft, proper installation and tuning are crucial for performance. If you are installing it yourself make sure you follow the manufacturer's guidelines for installation procedures, valve lash adjustment, and break-in procedures. Also its worth mentioning you should invest in a quality engine management system and work with your tuner to fine tune your LS engine for the best results and drivability.
In short choosing the right cam for you LS engine requires careful consideration of many factors. By understanding how you are going to use your vehicle, power goals you desire and what you want in the future from your car you should be able to make an informed decision on what camshaft is best for you and your vehicles application.
