Review HEDMAN Ls engine Swap Mid length Headers Gm Body Lsx fits 1964-67

The Hedman Hedders 68546 LS-engine swap mid-length headers are a High-performance exhaust solution designed specifically for 1964 to 1967 GM body vehicles undergoing an LSX engine swap. These headers are an essential component of the exhaust system, optimizing the flow of gases away from the engine, reducing backpressure, and enhancing performance.

Crafted from premium 321 stainless steel material, these headers prove to be both robust and lightweight. The mid-length design allows for improved exhaust flow, reducing positive and negative pulses for enhanced power and torque production. This design also enables a better fitment and clearance for various engine accessories and components.

The 68546 headers feature 1 5/8-inch primary tubes with 1 3/4-inch collectors. The bridge-lessCollectors design ensures an optimal flow, diminishing hot spots and increasing horsepower while maintaining an attractive appearance with its smooth, polished finish. Additionally, the built-in hood stack connection and OE conversions for the 6-bolt and 8-bolt patterns provide a seamless engine bay look and easy installation.

These headers are engineered for perfect fitment, offering clearance for engine accessories such as power steering, alternators, and air conditioning components. Their direct fitment with the stock exhaust and catalytic converter can facilitate a smoother and quicker swap process. Furthermore, they're compatible with factory exhaust manifolds when using steel catalytic converters.

Installing the Hedman Hedders 68546 LS-engine swap mid-length headers comes with several advantages, including improved power and torque production, augmented engine response, and a deeper, more resonant exhaust note. These headers exhibit distortion resistance and provide excellent durability, making them an investment worth making for any LSX-swapped GM vehicle.

Pros and Cons of Installing Hedman 68546 LS-Engine Swap Mid-Length Headers (1964-67 GM Bodies, 68543 LSX)

I. Introduction

The Hedman 68546 LS-Engine Swap Mid-Length Headers (AMipedia Part number: 68543 LSX) are designed for easy integration into 1964-1967 GM Body vehicles during engine swap projects. Before making a decision to purchase these headers, it is essential to evaluate their pros and cons.

II. Pros

1. Improved Airflow: Mid-length headers direct exhaust gases away from the engine sooner, providing more room for aftermarket intake systems and improved airflow.

2. Enhanced Power: The headers provide a better flow of exhaust gases, enabling a more consistent exhaust pulse to the collector. This leads to better engine efficiency, improving overall power output.

3. Better Sound: Mid-length headers offer a more pleasing exhaust note, thanks to their design and placement, making engine swaps sound more authentic.

4. Flexibility: These headers cater to a multitude of engine types in the GM family, making them a popular choice for custom builds and restorations.

5. Easy Installation: Hedman headers come with detailed installation instructions and are designed for simple and easy installation, saving time and effort during the swap process.

III. Cons

1. Expense: Hedman mid-length headers are higher-priced compared to stock headers due to their superior design and materials. This may discourage budget-conscious buyers.

2. Custom-designed engine harness: Depending on the specific engine in the vehicle, a custom wiring harness may be required for a successful installation as the stock harness might not fit seamlessly around the headers. While Hedman offers wiring harness solutions, additional cost and labor are associated with these parts.

3. Space constraints: Space can be a limiting factor when installing headers in 1964-1967 GM Body vehicles, as the engines might require trimming, relocations, or extensive modifications for proper clearance between headers and other parts.

4. Weight: The headers add weight to the engine due to their materials and design. This additional weight may negatively impact fuel economy, particularly in situations where minimal power gains result.

IV. Conclusion

The decision to buy Hedman's 68546 LS-Engine Swap Mid-Length Headers for a 1964-1967 GM Body vehicle depends on a number of factors, including budget, desired power gains, and engine compatibility. The headers offer significant benefits, such as improved exhaust flow, enhanced power, and a more authentic engine sound. However, they come with drawbacks like a higher price point, potential for custom engine harnesses, and weight gain.

For enthusiasts focusing on power and sound, the pros may outweigh the cons, but it's crucial to consider the resources and time required for a successful installation. Those with tighter budgets or space constraints might wish to explore alternative header solutions to achieve their goals without sacrificing too much engine performance or incurring additional expense.

V. Recommendation Before making a purchase, consider the following:

1. Clearly define project goals

2. Research engine compatibility and any engine harness requirements

3. Ensure adequate space for installation

4. Evaluate the budget for header costs and potential modifications

5. Consult with a knowledgeable mechanic or Hedman Technical Support for detailed advice

The Hedman 68546 LS-Engine Swap Mid-Length Headers represent a strong choice for power enthusiasts seeking a more authentic LSX engine sound and improved engine performance. However, their price, potential custom engine harness needs, and space restrictions are all important factors to consider before making the commitment.
