If you're not familiar with the term, camming a car refers to the process of modifying the camshaft in order to improve performance. The camshaft is responsible for opening and closing the valves in an engine, so by changing its shape, you can alter how much air and fuel gets into the cylinders. This can lead to more power, better throttle response, and improved fuel economy.
There are a few different ways to go about camming a car. You can install a larger or smaller camshaft, change the duration of the intake and exhaust strokes, or alter the lift of the valves. Each approach has its own set of benefits and drawbacks, so it's important to do your research before making any decisions.
Generally speaking, installing a larger cam will result in more power but less low-end torque. If you're planning on using your car for drag racing or other high-performance applications, this is usually the route you'll want to take. Shortening the intake stroke can also increase power while sacrificing some torque, but it's worth noting that this can lead to increased engine noise.
Finally, altering valve lift will change how much air and fuel gets into each cylinder
