The Mopar 440 engine is a classic powerhouse, known for its robust performance and reliability. For enthusiasts looking to upgrade their Mopar 440 to reach 480 horsepower, selecting the right components is crucial. This article will explore the best brands for headers, intake systems, and compression upgrades that can help you achieve this power goal.
Understanding the Mopar 440 Engine
The Mopar 440 is a big-block V8 engine produced by Chrysler from 1966 to 1978. With a displacement of 440 cubic inches, this engine was designed for performance and durability. To elevate its performance to 480 hp, several modifications can be made, including upgrading headers, intake systems, and increasing compression ratios.
Choosing the Right Headers
Headers play a critical role in improving exhaust flow and enhancing engine performance. Upgrading to high-performance headers can significantly increase horsepower and torque. Here are some of the best brands to consider:
- Hedman Hedders: Known for their durable construction and excellent fitment, Hedman headers provide a great balance of performance and affordability.
- Hooker Headers: A popular choice among enthusiasts, Hooker headers are designed for maximum flow and performance, making them ideal for high-horsepower builds.
- Doug’s Headers: These headers are custom-made for specific applications, ensuring optimal performance and fit for the Mopar 440.
Upgrading the Intake System
The intake system is vital for maximizing airflow into the engine, which is essential for achieving higher horsepower. When upgrading the intake for a Mopar 440, consider the following brands:
- Edelbrock: Their Performer RPM intake manifold is a favorite among Mopar enthusiasts, offering excellent performance across a wide RPM range.
- Holley: Known for their carburetors, Holley also produces high-performance intake manifolds that can significantly boost power and throttle response.
- Weiand: Their Stealth series intake manifolds are designed for optimal airflow and are a great choice for those looking to maximize horsepower.
Increasing Compression Ratios
Increasing the compression ratio of your Mopar 440 is another effective way to boost horsepower. Higher compression allows for more power to be generated from the same amount of fuel. Here are some brands that offer high-performance pistons and components for increasing compression:
- Wiseco: They offer high-performance forged pistons that are designed to withstand higher compression and provide excellent durability.
- Speed Pro: Known for their quality piston rings and components, Speed Pro offers products that can help you achieve the desired compression ratio.
- TRW: Their pistons are designed for high-performance applications and can help increase the compression ratio while maintaining reliability.
Combining Upgrades for Maximum Performance
To achieve the desired 480 horsepower from your Mopar 440, it’s essential to combine these upgrades effectively. Here are some tips for maximizing your performance:
- Choose a compatible set of headers and intake that work well together to ensure optimal airflow.
- Consult with a performance engine builder to determine the best compression ratio for your specific setup.
- Consider tuning your engine with a high-performance carburetor or fuel injection system to optimize fuel delivery.
Conclusion
Upgrading your Mopar 440 to reach 480 horsepower is an achievable goal with the right components. By selecting high-quality headers, intake systems, and increasing compression ratios, you can unleash the full potential of this classic engine. Always ensure that your upgrades are compatible and consider professional assistance for the best results.
