Review GENERAL MOTORS Original #9796155 Lh Side Exhaust Manifold Date fits FIREBIRD 400 350 1969

The **Ford 9796155 1969 1970 Firebird LH Exhaust Manifold (Part #F-25-9)** is a meticulously engineered, high-performance component designed to deliver optimal exhaust flow and structural integrity for the iconic 350 cubic-inch V8 engines found in the first-generation Ford Thunderbird and Mercury Cougar, as well as the Firebird and Cougar models from the late 1960s. Crafted from high-quality cast iron, this exhaust manifold is built to withstand the intense heat and pressure generated by the powerful pushrod V8s that powered these classic muscle cars, ensuring durability while maintaining precise fitment to the engine s cylinder heads. The manifold features a robust, dual-exhaust design with smooth, tapered passages that minimize backpressure, allowing exhaust gases to exit the engine bay with greater efficiency, which in turn enhances engine breathing and overall performance. The casting includes precise bolt patterns and alignment holes, ensuring a secure and leak-free connection to the cylinder heads, while the integrated gasket surfaces provide a tight seal against exhaust gases. This manifold is a direct replacement for the original equipment (OEM) part, maintaining the exact dimensions and mounting points required for a perfect fit on 1969 1970 Firebird LH (left-hand drive) models equipped with the 350ci V8, including both the 2-barrel and 4-barrel carbureted configurations. Whether restoring a vintage Firebird to its original glory or upgrading an existing exhaust system for improved performance, this manifold serves as a reliable and authentic choice, preserving the mechanical integrity and classic character of these legendary American muscle cars.

### **Pros and Cons of buying a 9796155 (1969 400 350 Firebird LH Exhaust Manifold F-25-9)**

1. **OEM Replacement Part** This is an original equipment manufacturer (OEM) exhaust manifold, meaning it is designed to fit perfectly with the 1969 400/350 Firebird LH engine without modifications. It ensures proper fitment, alignment, and functionality.

2. **Durability and Performance** The F-25-9 manifold is built to withstand high temperatures and engine stress, reducing the risk of premature failure. It helps maintain proper exhaust flow, which can improve engine efficiency and power output.

3. **Compatibility with Stock and Modified Engines** Since it is an OEM part, it works well with both stock engines and those with minor modifications (e.g., performance camshafts, headers, or mild tuning). It is not designed for extreme high-performance builds but is a solid choice for daily drivers or mildly modified vehicles.

4. **Easy Installation** Being an OEM part, it should come with necessary gaskets, bolts, and sometimes even installation instructions. This makes the replacement process straightforward for those with basic mechanical skills.

5. **Reliability** GM s older exhaust manifolds (especially from the 1960s 1970s) were generally well-built. This part is unlikely to fail prematurely if installed correctly and maintained properly.

6. **Aesthetic Fit** If you value authenticity, this manifold matches the original appearance of the engine bay, which can be important for classic car enthusiasts.

7. **Warranty Coverage (If Purchased from a Reputable Seller)** Some sellers offer warranties or return policies, providing peace of mind in case of defects.

---

1. **Age and Potential Wear** Since this is a used or reconditioned OEM part (especially if sourced from a salvage yard or aftermarket supplier), it may have signs of wear, rust, or previous damage. A thorough inspection is necessary to ensure it is in good condition.

2. **Limited Performance Gains** While it maintains proper exhaust flow, it is not a high-performance part. If you are running headers or a supercharger, this manifold may not be ideal as it lacks the flow benefits of aftermarket alternatives.

3. **Potential for Leaks** Older exhaust manifolds can develop cracks or leaks over time, especially if the vehicle has been driven in harsh conditions (e.g., salted roads, extreme heat). A pre-purchase inspection is critical.

4. **Cost Compared to Aftermarket Options** While not excessively expensive, this OEM part may be more costly than aftermarket alternatives that offer similar or better performance (e.g., headers or high-flow manifolds). However, aftermarket parts may not be as reliable for daily driving.

5. **Installation Challenges** If the original manifold was damaged or warped, removing it can be tricky. Some Firebird LH engines have tight spaces around the manifold, requiring patience and possibly additional tools (e.g., a manifold breaker bar).

6. **Rust and Corrosion Risk** If the part has been sitting in storage for a long time or was exposed to moisture, rust can be an issue. A thorough cleaning and inspection are necessary before installation.

7. **Limited Availability of New OEM Parts** Since this is an older model, finding a brand-new OEM manifold may be difficult. Most available options are likely reconditioned or used, which introduces uncertainty about their condition.

The **9796155 (1969 400/350 Firebird LH Exhaust Manifold F-25-9)** is a solid choice if you prioritize **reliability, OEM fitment, and ease of installation** for your classic Firebird. It is ideal for **daily drivers, stock or mildly modified engines**, and enthusiasts who value authenticity. However, if you are pursuing **high-performance modifications** (e.g., headers, forced induction, or aggressive tuning), an aftermarket high-flow manifold or headers may be a better investment.

- You need a direct OEM replacement for stock or lightly modified performance.

- You have confirmed the part is in good condition (no cracks, rust, or warping).

- You are comfortable with basic engine bay work and have the tools to install it properly.

- You value the classic look and reliability over extreme performance gains.

- You are running headers or a supercharger, in which case a high-flow manifold or headers would be more beneficial.

- You want to avoid potential rust or wear issues, and a new or heavily reconditioned aftermarket part is available at a similar price.

- You are unsure about the part s condition and cannot inspect it in person (in which case, buying from a trusted seller with a warranty is crucial).

**Final Tip:** Always inspect the part closely for cracks, rust, or damage before purchasing. If possible, test-fit it in your engine bay to ensure it aligns correctly. For maximum longevity, apply a high-temperature gasket maker and torque the bolts to the manufacturer s specifications.
