Project Sleeper: Upgrading the Intake Manifold and Carburetor

🚀The Holly Street Dominator manifold was designed with the factory heads in mind and works well with stock or modified engines.

🐚The small cross-sectional area of the manifold creates high port speeds, resulting in better fuel atomization and foot-pounds of torque.

💪The Holly Street Dominator manifold is a great choice for sporty trucks that need mid-range torque and top-end horsepower.

🛠Port matching the manifold to the cylinder heads improves airflow and reduces restrictions, resulting in increased power.

💪Modifying the intake manifold can be an effective alternative to a cam swap, achieving similar power gains.

Why is the Holly Street Dominator manifold a popular choice?

—The Holly Street Dominator manifold is popular because it was designed to work well with factory heads and provides good performance gains.

What are the benefits of using a small cross-sectional area manifold?

—A small cross-sectional area manifold creates high port speeds, leading to better fuel atomization and increased foot-pounds of torque.

Is the Holly Street Dominator manifold suitable for trucks?

—Yes, the Holly Street Dominator manifold is a great choice for sporty trucks that require both mid-range torque and top-end horsepower.

How does port matching the manifold improve performance?

—Port matching the manifold to the cylinder heads improves airflow and reduces restrictions, resulting in increased power.

Why is modifying the intake manifold a good alternative to a cam swap?

—Modifying the intake manifold can achieve similar power gains as a cam swap, making it a cost-effective option.
