The Mopar 440 engine is a legendary powerplant known for its performance and reliability. When building a high-performance 440, enthusiasts often aim for impressive horsepower figures. In this article, we will explore how to achieve 600 horsepower using Dart heads and an Edelbrock supercharger.
Understanding the Mopar 440 Engine
The 440 cubic inch V8 engine was introduced by Chrysler in the 1960s. It quickly gained a reputation for being a robust engine that could handle high power outputs. The 440 was commonly used in muscle cars and has remained a favorite among performance enthusiasts.
Key Components for a 600 HP Build
- Dart Cylinder Heads
- Edelbrock Supercharger
- Performance Camshaft
- High-Performance Fuel System
- Upgraded Ignition System
Dart Cylinder Heads: The Heart of Performance
Dart heads are known for their superior airflow and performance. When selecting Dart heads for your 440 build, consider the following:
- Material: Aluminum heads are lighter and provide better heat dissipation.
- Porting: Choose heads that are pre-ported for optimal airflow.
- Compression Ratio: Aim for a compression ratio of 9.5:1 to 10.5:1 for supercharging.
Edelbrock Supercharger: Boosting Power
The Edelbrock supercharger is designed to increase horsepower and torque significantly. Here’s how to integrate it into your build:
- Type: Choose a supercharger that suits your performance goals, such as a roots or twin-screw design.
- Installation: Ensure proper mounting and alignment with the engine.
- Boost Levels: Aim for a boost level of 6-8 psi for reliability and performance.
Performance Camshaft Selection
A high-performance camshaft is crucial for maximizing engine output. Consider the following factors when selecting a cam:
- Lift and Duration: A cam with higher lift and longer duration will improve airflow.
- RPM Range: Choose a cam that matches your desired power band.
- Compatibility: Ensure the cam is compatible with your Dart heads and supercharger setup.
Fuel System Upgrades
To achieve 600 hp, your fuel system must be able to deliver the necessary fuel flow. Upgrades include:
- Fuel Pump: Install a high-flow fuel pump to meet the increased demand.
- Fuel Injectors: Use larger injectors to ensure proper fuel delivery.
- Fuel Lines: Upgrade to larger diameter fuel lines to reduce restrictions.
Ignition System Enhancements
An upgraded ignition system is essential for reliable performance. Key components include:
- Ignition Coil: Choose a high-output ignition coil for better spark energy.
- Distributor: Consider a performance distributor for improved timing accuracy.
- Spark Plugs: Use colder spark plugs to prevent detonation under boost.
Final Assembly and Tuning
Once all components are selected and installed, proper tuning is crucial to achieve 600 hp. Follow these steps:
- Engine Break-In: Follow a proper break-in procedure to ensure longevity.
- Tuning Software: Use appropriate tuning software to adjust fuel maps and timing.
- Dyno Testing: Consider dyno testing to measure horsepower and torque outputs.
Conclusion
Building a high-performance Mopar 440 engine capable of producing 600 hp is an achievable goal with the right components and tuning. By utilizing Dart heads, an Edelbrock supercharger, and upgrading critical systems, enthusiasts can create a powerful and reliable engine that stands out on the road or the track.
