The design incorporates **adjustable height and angle settings**, allowing for fine-tuned alignment with the transmission, driveshaft, and suspension components, ensuring optimal clearance and operation critical for both street and track applications. Whether you're running a **4-speed manual, TorqueFlite, or A833 automatic**, the B6X135 system provides a **universal fit** with minimal modification required, making it ideal for restomods, drag builds, or high-mileage daily drivers. Backed by BFO s reputation for durability and performance, this kit is not just an upgrade it s a **game-changer** for anyone serious about preserving or enhancing the integrity of their classic Dodge s legendary big-block power.

### **Pros and Cons of Buying a BFO B6X135 Conversion Kit for a 1966-72 B-Body or 1970-74 E-Body with a 383/440 Motor Mount**

#### **Pros**

1. **Improved Engine Bay Organization**

- The BFO B6X135 conversion kit replaces the stock, often cluttered and poorly designed engine bay with a clean, modular system. This reduces the risk of accidental damage to components like the distributor, alternator, and wiring harness.

- The new mount provides better access to critical parts, making maintenance and repairs easier.

2. **Better Engine Support and Alignment**

- The stock B-body and E-body motor mounts are known for sagging over time, leading to misalignment of the engine, transmission, and drivetrain. The B6X135 conversion uses a more robust, adjustable mount system that helps maintain proper alignment, reducing stress on the transmission and drivetrain components.

- This can prevent premature wear on the transmission bellhousing, flywheel, and even the engine itself.

3. **Compatibility with Modern and Aftermarket Parts**

- The B6X135 mount is designed to work with a wide range of aftermarket components, including high-performance exhaust headers, fuel injection systems, and modern alternators.

- It is also compatible with the **B6X135** and **B6X135M** kits, which offer additional features like a **transmission tunnel shield** and **exhaust heat shielding**, improving longevity and performance.

4. **Reduced Heat Transfer to Suspension Components**

- The stock motor mounts allow excessive heat from the engine and exhaust to transfer to the frame and suspension, potentially warping brackets and weakening suspension components.

- The B6X135 conversion includes **heat shields** that direct heat away from critical areas, reducing the risk of frame rot and suspension damage.

5. **Easier Installation of Aftermarket Accessories**

- Many modern accessories, such as **performance air cleaners, oil catch cans, and high-flow alternators**, require a more structured engine bay.

- The B6X135 mount provides the necessary clearance and support for these upgrades without interfering with other components.

6. **Improved Reliability for High-Performance Applications**

- If you plan to run a **high-torque engine (e.g., a 440, 426 Hemi, or turbocharged 383)**, the stock mounts may not be sufficient. The B6X135 conversion is designed to handle the extra stress, reducing the likelihood of drivetrain issues.

7. **Aesthetic and Cleaner Look**

- The stock motor mounts are often rusted, bent, or missing, giving the engine bay a neglected appearance. The B6X135 conversion provides a **neat, factory-like look** with proper alignment and minimal clutter.

---

#### **Cons**

1. **Cost**

- The BFO B6X135 conversion kit is not cheap, typically ranging from **$200 to $400**, depending on whether you opt for the basic **B6X135** or the more comprehensive **B6X135M** (which includes additional shields and mounts).

- If you re on a tight budget, this may be a significant expense, especially if you re restoring a project car.

2. **Installation Complexity**

- Remove the engine and transmission (or at least disconnect them).

- Modify or replace existing brackets and mounts.

- Ensure proper alignment of the transmission and driveshaft.

- If you re not comfortable with engine work, you may need to pay a mechanic, adding to the cost.

3. **Potential for Misalignment if Not Installed Correctly**

- If the new mounts are not properly aligned with the transmission and driveshaft, you could introduce **driveshaft vibration, transmission strain, or even a binding driveshaft**.

- This risk is mitigated by following the installation instructions carefully, but it s still a consideration.

4. **Limited Availability of Stock Parts for Original Mounts**

- While the B6X135 kit is a great upgrade, if you ever need to **reverse the modification** (e.g., for a different project), finding original OEM mounts may be difficult, as they are no longer widely produced.

5. **May Not Be Necessary for Low-Mileage or Well-Maintained Cars**

- If your B-body or E-body has **low miles, a well-supported engine, and no signs of sagging or misalignment**, the stock mounts may still function adequately.

- In such cases, the cost of the conversion may not be justified unless you re planning major modifications.

---

### **Conclusion**

The **BFO B6X135 conversion kit** is one of the best upgrades you can make for a **1966-72 B-body or 1970-74 E-body** running a **383 or 440 motor**. It addresses long-standing issues with **poor engine support, heat transfer, and drivetrain stress**, while also improving reliability and making aftermarket modifications easier.

- Plan to run a **high-performance or high-torque engine** (e.g., 440, 426 Hemi, turbo 383).

- Want a **cleaner, more organized engine bay** for maintenance.

- Are concerned about **long-term reliability** of your drivetrain.

- Intend to install **aftermarket accessories** that require proper mounting.

**Then the B6X135 conversion is highly recommended.**

- Have a **low-mileage, well-maintained car** with no visible issues.

- Are on a **tight budget** and the stock mounts still function adequately.

- Are not planning **major modifications** in the near future.

**Then the cost may not be justified, and you could consider other upgrades first.**

---

### **Final Recommendation**

For **most serious enthusiasts restoring or modifying a B-body or E-body with a 383/440**, the **BFO B6X135 conversion is a worthwhile investment**. It provides **long-term reliability, better performance, and easier maintenance**, making it one of the best **bang-for-your-buck** upgrades available.

- **Transmission tunnel shield** (if not included in the B6X135M kit).

This will ensure your **Mopar muscle car remains a reliable and enjoyable project for years to come.**
