If the engine is considered the heart of the car, the cam is the blood vessel that supplies fuel for the engine to work. Cam works by rotating and creating torque to help open and close the energy supply and exhaust valve. A good Cam will provide enough fuel to help the engine run smoothly.
Moreover, the perfect cam can increase the horsepower of the machine many times over. This article will show you how to choose the biggest cam for stock 350 chevy engine.
Features of a perfect Cam For Stock 350
A perfect cam will help the engine operate at full capacity and ensure a long engine life. Not all expensive or featured cam sets are good for your camera. So, you must choose the right cam set according to the required parameters of the engine.
For the stock 350 chevy engine, you need to note the following characteristics of the cam set.
Operating range (RPM range)
RPM operating range is the most important indicator of the cam because they determine the amount of fuel injected and the power generated. In addition, the RPM range characterizes the rotational speed of the Cam.
Accordingly, if the RPM is too low, the engine will not operate at the right capacity and is easily damaged.
Conversely, too high RPM puts too much pressure on the engine and destroys it. So the suitable operating range for stock 350 is around 2000 – 6500 RPM.
Lobe separation angle and valve lift
Lobe’s angle helps to ensure smooth and continuous opening and closing of the fuel and exhaust valves. Streetcar engines need a wide lobe angle while racing cars need a narrow lobe angle for high speed.
For a 350 stock chevy engine, a suitable lobe separation angle is 107 – 108 degrees. In addition, the valve lift should be between 0.479” – 0.480”.
Size of Cam
The larger the size of the cam, the more energy is required to operate the valve lift. Obviously, the biggest cam for stock 350 will take more energy.
Each size will have its purpose, so choose the right sized cam for the potential and power of the engine. Cams that are too large will also harm the engine of the machine.
Torque requirement
Besides the size, you need to pay attention to the torque parameter of the cam. Torque is also the indicator that determines the horsepower of the engine. Therefore, you need to choose a set of cams with torque parameters suitable for the machine’s engine.
