Like many other car owners, I am also obsessed with getting more and more horsepower out of car engines. Why not? It’s the best thing for your car and wallet. So I look up to a performance Cam for the engine as it certainly adds power to the engine.
Cam is the shorthand for camshaft. It is a metal rod operating in the engine. Changing this component can increase the performance of the engine in a particular RPM range. However, it’s a challenging task to get a performance Cam while still maintaining excellent driveability.
Let’s make it easy for you. I have dug out the 5 best cams for LQ4 with 317 heads. So go through them and get your best-suited one. Also, read the buying guide and relevant question answers.
What Is A Cam For LQ4 With 317 Heads?
Each car engine has one or more cams. A camshaft is a type of rod containing some irregular lobes. It is an essential part of the engine design. When the part rotates, the valve opens and closes, and the air-fuel mixture gets in and out of the combustion chamber.
The Cam’s lobes activate the engine’s intake and exhaust valves. One of the lobes opens the intake valve, and the following one opens the exhaust valve. And the shaft continuously rotates and operates the valve at the appropriate timing. It is a well-choreographed arrangement that recounts hundreds of times in one minute.
A camshaft determines how the engine performs as it fixes the duration and nature of the combustion chamber. For example, the intake valve can open for a longer or shorter period for a cam. That means a short change in this duration can make a big difference.
Why do you Need a Camshaft?
If your vehicle has an LQ4 engine with 317 heads, then you should immediately jettison the original camshaft because the original camshaft is small and affects the engine’s performance. So changing the camshaft will be more effective, rather than installing a power adder.
Furthermore, the engine will have a noticeable HP boost. When a cam modifies the time duration of the engine valve, ultimately, it increases the horsepower output.
According to car enthusiasts, replacing the camshaft can add more than a 10% HP boost, although the result may vary due to engine type and size.

Buying Guide For the Best Cam for LQ4 with 317 Heads

Since you are installing the cam kit to improve vehicle performance, ensure that Cam’s profile is better suited to your engine model and effectively works for it. Consider the lift and duration, which is the primary factors. It measures in degrees of crank rotation.
Adding horsepower is the main purpose of replacing the camshaft of the engine. So before buying the kit, thoroughly scan how much horsepower it adds to your vehicle. Also, consider the torque output and RMP range of the camshaft.
The materials of the camshaft directly affect the service lifespan. The durable camshaft doesn’t wear out and break easily. As a result, it won’t have premature damage. So always consider robust and solid materials while choosing it.
In terms of cam selection, you should consider newer developments of camshaft cores. Choosing high-strength cores is necessary as it allows larger gun drills through the camshaft. In turn, there will be less rotating mass and decreased power losses.
Actually, the duration fixes how big the camshaft is. A big cam opens for a longer duration, which means it opens the valve larger. On the contrary, a short cam opens for less duration. You should always seek a big camshaft as it increases top-end power to the low-end torque. Small Cam provides less boost and drivability.
