Review EDELBROCK Chrysler Gen 5.7l /370 6.1l /392 6.4l Part 364 fits HEMI 345
The Edelbrock 3647 Performer RPM Air-Gap Intake Manifold is a high-performance solution designed specifically for Chrysler Gen III HEMI engines, including those with displacements of 345 cubic inches (5.7L), 370 cubic inches (6.1L), and 392 cubic inches (6.4L). This intake manifold is part of Edelbrock's Performer series, which is renowned for delivering exceptional power gains and improved drivability on all modern HEMI applications.
The manifold features an oversized runner design that ensures an optimal flow rate for improved combustion efficiency and power output. The air-gap design between the intake runners and the throttle body enhances the velocity of airflow, resulting in a more consistent and responsive throttle performance.
The 3647 intake manifold comes with a high-performance, vacuum-secondary 650-cfm Edelbrock Quadra-Jet carburetor. This carburetor is designed to complement the high-performance intake manifold and delivers the precise fuel mixture catalytic converters require for optimal operation. The carburetor also comes with a built-in accelerator pump and electric choke, providing smooth cold-start characteristics and great driveability.
The 3647 intake manifold is made from high-strength aluminum, ensuring light weight and excellent heat dissipation. It also features integrated fuel rails that are precision-machined for accurate fuel delivery. The manifold is also R km/h ground clearance certified, ensuring compatibility with factory emissions equipment.
The manifold's runner design and dimensions have been optimized to provide improved torque and power gains across the entire RPM range. This makes it an excellent choice for both street and race applications. In addition, the intake manifold's fit and finish is of the highest order, ensuring a perfect installation and alignment with the engine and other components.
This intake manifold is a direct replacement for the stock intake and comes with all necessary hardware for installation. It also features a detailed installation guide to ensure a hassle-free installation process. With the Edelbrock 3647 Performer RPM Air-Gap Intake Manifold, Chrysler Gen III HEMI owners can expect a significant increase in power and torque, as well as improved throttle response, making their vehicles perform like never before.
The Edelbrock 3647 Performer Series E- uncomfortable gas pedalsPPC intake manifold is a popular upgrade option for Chrysler Hemi engines, specifically the 345 5.7L, 370 6.1L, and 392 6.4L models. Here are some pros and cons to consider before purchasing.
Pros:1. Increased horsepower: The Edelbrock intake manifest provides better airflow and volumetric efficiency, leading to an increase in horsepower. The exact amount of horsepower gained depends on the specific engine and tuning, but most reports indicate gains of around 20-30 horsepower.
2. Improved throttle response: The Edelbrock intake manifold provides smoother and quicker throttle response, which results in better driveability and a more responsive engine.
3. Enhanced engine sound: The intake manifold also contributes to a pleasant engine sound that enhances the overall driving experience.
4. Fuel economy: Despite the slight increase in power, some drivers have reported improved fuel economy with the Edelbrock intake manifold.
Cons:1. Complex installation: Installing the Edelbrock intake manifold can be a complex process, especially for those with little to no experience in engine modification. It may require the use of special tools and the modification of existing engine components.
2. Expensive: Compared to other intake manifolds on the market, the Edelbrock 3647 is relatively expensive. The cost of the manifold alone can range from $500 to $1,000 or more, depending on the specific engine size.
3. Fuel trim issues: Some drivers have reported fuel trim issues after installing the Edelbrock intake manifold. Fuel trim is the system that adjusts fuel delivery to maintain the ideal air-fuel mixture in the engine. This issue may require additional tuning or reflashing of the engine's computer.
4. Uncomfortable gas pedal: Some drivers have reported that the installation of the Edelbrock intake manifold can cause the gas pedal to become uncomfortable or difficult to press down, requiring greater force to activate the throttle.
Conclusion:The Edelbrock 3647 Performer Series E-GAS intake manifold is an excellent upgrade option for Chrysler Hemi engines, providing increased horsepower, improved throttle response, and an enhanced engine sound. However, it is a complex and expensive modification that requires specialized installation and may cause fuel trim issues or uncomfortable gas pedal sensations.
Recommendation:If you're a DIY enthusiast with a good understanding of engine modification, the Edelbrock intake manifold can be a worthwhile investment for your Chrysler Hemi engine. However, it's essential to weigh the pros and cons carefully and consider your budget, installation capabilities, and the potential complications involved. If you're not confident in your abilities, it's recommended that you work with a professional mechanic to ensure a successful and safe installation. Alternatively, there are other less complex and less expensive intake manifold options available on the market that can still provide significant power gains.
