A race camshaft, also known as a race cam, is an essential component in high-performance engines used for various racing applications. Whether it’s drag racing, street racing, or even circle track racing, a race cam plays a crucial role in optimizing engine power and performance.
So, what exactly does a race cam do and how does it differ from a regular street cam? Let’s dive deeper into this topic to gain a better understanding.

The Purpose of a Race Camshaft
A race camshaft is specifically designed to maximize engine power output by optimizing valve lift and duration. Unlike a street cam, which focuses on emissions and fuel efficiency, a race cam prioritizes performance above all else.
One of the key characteristics of a race cam is its fast valve lift rate. This means that the camshaft opens the valves earlier and keeps them open for a longer duration, allowing more air and fuel to enter the combustion chamber. This increased airflow results in improved horsepower and torque, particularly at higher engine RPMs.
Differences Between a Race Cam and a Street Cam
While both race cams and street cams have the same basic function of controlling valve timing, there are significant differences between the two:
- Lift and duration: A race cam typically has higher lift and longer duration than a street cam.
- Valve overlap: Race cams often have more valve overlap, which is the period when both the intake and exhaust valves are partially open. This improves scavenging and exhaust flow.
- Idle quality: Because race cams are optimized for high performance, they may produce a rough idle compared to a smoother idle of a street cam.
It’s important to note that a race cam may not be suitable for daily driving or street use. The aggressive profile of a race cam can have a negative impact on low-end torque and drivability, making it less desirable for regular street driving.

Applications of a Race Camshaft
Race camshafts are widely used in various racing applications, including:
- Drag racing: Where the focus is on achieving maximum horsepower and acceleration in a straight line.
- Street racing: For those who want to gain an advantage in illegal or organized street races.
- Circle track racing: In oval track racing, where high-speed cornering and acceleration are crucial.
In addition to these racing disciplines, race cams can also be utilized in specific performance-oriented street cars. However, it’s important to consider the intended use and overall drivability of the vehicle before installing a race cam.
Frequently Asked Questions For What Is A 34 Race Cam
What’s A 3 4 Race Cam?
A 3 4 race cam is a camshaft that is optimized for racing purposes. It is designed to maximize power and performance in a racing engine by providing fast valve lift rates and high amounts of valve lift. This allows for better airflow into the combustion chamber, resulting in improved engine performance.
What Does A Race Camshaft Do?
A race camshaft is designed to optimize power and performance in racing engines. It has faster valve lift rates and higher amounts of valve lift, which allows more air and fuel to enter the combustion chamber. This results in increased horsepower and torque, especially at higher RPMs.
A race camshaft is not focused on emissions or fuel economy, but rather on maximizing engine performance on the track.
What Does A Bigger Cam Do?
A bigger camshaft can increase valve lift and duration, allowing more air and fuel into the combustion chamber. This can improve engine performance, especially at higher RPMs, by increasing horsepower and torque.
What Does 4 Cam Mean?
A 4 cam refers to an engine configuration with four camshafts, which control the opening and closing of the engine’s valves. This setup is commonly found in high-performance and racing engines, allowing for better control over valve timing and improved power output.
What Is A 34 Race Cam And How Does It Differ From A Standard Camshaft?
A 34 Race Cam is a high-performance camshaft designed specifically for racing applications. It offers a more aggressive profile than a standard camshaft, resulting in increased valve lift and duration. This allows for better airflow into the combustion chamber, leading to improved engine performance and horsepower.
Conclusion
A race camshaft is an integral part of high-performance engines used in racing applications. It maximizes engine power and performance by optimizing valve lift and duration. While a race cam offers significant benefits in terms of horsepower and torque, it may not be suitable for regular street driving due to potential drivability issues.
Ultimately, the choice between a race cam and a street cam depends on the specific requirements and goals of the engine and its intended use. Consulting with a professional engine builder or performance specialist is recommended to ensure the best selection for optimal performance.
