by

The Chevy 383 Stroker engine is a popular choice among performance enthusiasts looking to achieve impressive horsepower numbers. With the right camshaft and intake manifold combination, reaching 450+ horsepower is not only possible but also achievable with the right tuning and supporting modifications. In this article, we will explore some of the best cam and intake combos that can help you unlock the full potential of your Chevy 383 Stroker.

Understanding the Chevy 383 Stroker Engine

The Chevy 383 Stroker is essentially a small-block engine that has been modified to increase its displacement to 383 cubic inches. This increase in displacement allows for greater airflow and fuel delivery, which are critical for generating higher horsepower. The key components that contribute to this increase in performance include the crankshaft, pistons, and camshaft.

Choosing the Right Camshaft

The camshaft plays a crucial role in determining the engine’s performance characteristics. When selecting a cam for your 383 Stroker, consider the following factors:

  • Lift: The amount of lift affects how much air and fuel can enter the combustion chamber.
  • Duration: Duration affects the timing of the valve openings and closings, impacting power band and idle quality.
  • LSA (Lobe Separation Angle): Affects the overlap between intake and exhaust valves, influencing idle and power characteristics.
  • Comp Cams Xtreme Energy 274H: Known for its aggressive profile, it offers a great balance of power and drivability.
  • Howards Cams 110241-10: A solid choice for achieving a broad power band with excellent torque.
  • Summit Racing SUM-8700: This cam provides a good compromise between performance and streetability.

Choosing the Right Intake Manifold

The intake manifold is another critical component that can significantly affect engine performance. It is responsible for directing air and fuel into the combustion chamber. When selecting an intake manifold for your 383 Stroker, consider the following:

  • Type: Choose between single-plane and dual-plane designs based on your performance goals.
  • Material: Aluminum intakes are lighter and provide better performance, while cast iron is more durable.
  • Port Size: Ensure the intake ports match your cylinder heads for optimal airflow.
  • Edelbrock Performer RPM: A versatile dual-plane intake that provides great torque and horsepower.
  • Holley Strip Dominator: A single-plane intake designed for high RPM performance, perfect for racing applications.
  • Summit Racing Dual Plane Intake: Offers excellent performance for street applications with a good power band.

Combining Cam and Intake for Maximum Performance

To achieve the desired horsepower, it’s essential to combine the right camshaft with an appropriate intake manifold. Here are some effective combinations that can help you reach 450+ horsepower:

  • Comp Cams Xtreme Energy 274H + Edelbrock Performer RPM: This combo provides a strong mid-range power and excellent throttle response.
  • Howards Cams 110241-10 + Holley Strip Dominator: Ideal for high-performance applications, this pairing excels at higher RPMs.
  • Summit Racing SUM-8700 + Summit Racing Dual Plane Intake: A great choice for daily drivers looking for balanced performance.

Supporting Modifications

To maximize the performance of your 383 Stroker with the selected cam and intake combination, consider the following supporting modifications:

  • Upgraded Cylinder Heads: High-flow heads can significantly improve airflow and overall performance.
  • High-Performance Exhaust System: A free-flowing exhaust system will help expel gases more efficiently.
  • Fuel System Upgrades: Ensure your fuel pump and injectors can supply enough fuel for your performance goals.
  • Tuning: Proper tuning is essential to optimize performance and ensure reliability.

Conclusion

Achieving 450+ horsepower from a Chevy 383 Stroker is attainable with the right camshaft and intake manifold combinations. By selecting the best components and considering supporting modifications, you can unlock the full potential of your engine. Whether you are building a street machine or a race car, the right choices will lead you to an exhilarating driving experience.
