The **Dodge 546 CH8586 (1980 1991) Ram 150/250/350 with Manual Transmission Bar** is a rare and highly sought-after piece of automotive history, embodying the raw, unfiltered power and rugged simplicity of America s muscle truck era. Built between 1980 and 1991, this iconic **318 cubic inch (5.2L) inline-six engine** originally designed for the Dodge Dart and Monaco was later repurposed into the **Ram 150, 250, and 350** series, where it became a cult favorite among enthusiasts for its balance of torque, durability, and off-road capability. The **CH8586** designation refers to a specific engine variant, often equipped with a **single-barrel Carter carburetor** (though later models may feature a **Holley or Rochester carb**) and paired with a **three-speed manual transmission**, delivering a driving experience that is both engaging and brutally honest. The **manual transmission bar** a critical component for shifting is a key feature, allowing drivers to manually select gears via a floor-mounted shifter, offering a tactile connection to the engine s raw power. This setup was particularly popular in the **Ram 250 and 350** models, which were often built for towing, hauling, and off-road adventures, where the **318 s** 200 220 horsepower (depending on tuning) and **280 lb-ft of torque** made it a formidable workhorse. The **1980 1991 Ram series** was known for its utilitarian design, with a **boxy, angular body style**, heavy-duty suspension, and a **unibody construction** that, while not as refined as later models, offered exceptional durability. The **manual transmission bar** often found in later years was an aftermarket or factory upgrade that replaced the traditional column shifter, providing a more driver-centric experience. This engine and transmission combination was also a favorite for **hot rodding and street racing**, where its simplicity allowed for easy modifications, from **high-performance carburetors and exhaust systems** to **performance camshafts and headers**. Today, the **Dodge 546 CH8586 318** remains a symbol of American automotive ingenuity, prized by collectors, restorers, and enthusiasts who appreciate its no-nonsense power and timeless appeal. Whether used in a **restored daily driver, a towing beast, or a street-legal hot rod**, this engine and transmission setup continues to turn heads and inspire a new generation of mechanics and gearheads.
### **Pros and Cons of Buying a 1980 1991 Dodge Ram 50 Series (D150/D250/D350) with Manual Transmission**
#### **Pros**
1. **Strong Engine and Towing Capacity**
- The **546 inline-six engine** (318 or 360 cubic inches) is a robust, heavy-duty powerplant designed for towing and hauling. It s known for reliability when properly maintained.
- The **D150/D250/D350** designations indicate increasing payload capacities, making these trucks suitable for serious work (e.g., farming, construction, or heavy-duty towing).
- The **manual transmission** (typically a **4-speed or 5-speed**) allows for better control in demanding driving conditions, such as steep grades or off-road use.
2. **Durable and Simple Construction**
- The **boxed-steel frame** and **heavy-duty suspension** (with optional heavy-duty springs and shocks) make these trucks built to last, especially in rugged applications.
- Many components (e.g., brakes, drivetrain) are **easier to repair** than modern electronics-heavy systems, reducing long-term costs if you re mechanically inclined.
- The **mechanical fuel injection (MFI) or carbureted engines** (depending on model year) are simpler than modern fuel-injected systems, though they require more maintenance.
3. **Off-Road and Utility Potential**
- With the right modifications (lift kits, locking differentials, heavy-duty tires), these trucks can handle **off-roading, rock crawling, or overlanding** better than many modern trucks in the same class.
- The **high ground clearance** (especially on D350 models) and **strong chassis** make them versatile for agricultural or industrial use.
- The **manual transmission** is ideal for **hill climbing, trail driving, or towing heavy loads** where a clutch-controlled shift is preferable.
4. **Lower Cost of Ownership (If Maintained)**
- **Parts are widely available and affordable**, especially for common models like the **360 V8 (in later years)** or **318 inline-six**.
- **Labor costs** for basic repairs are lower than on modern trucks, though specialized work (e.g., transmission rebuilds) may require a skilled mechanic.
- **Fuel efficiency is decent for a heavy-duty truck** expect **10 15 MPG** in mixed driving, which is better than many modern diesel trucks in similar classes.
5. **Classic Truck Appeal and Customization**
- These trucks are **highly sought-after by enthusiasts**, meaning a well-maintained example can **retain or even appreciate in value** over time.
- The **manual transmission** adds to their **vintage charm**, making them popular for **restomod projects, hot rods, or show trucks**.
- **Aftermarket support** is strong you can find **performance parts, suspension upgrades, and custom builds** tailored to these trucks.
6. **Reliability in the Right Hands**
- With **proper maintenance** (regular oil changes, transmission fluid flushes, brake inspections), these trucks can **last 300,000 miles**.
- The **mechanical nature** of the drivetrain means fewer electronic failures compared to modern trucks.
---
#### **Cons**
1. **High Maintenance Requirements**
- **Manual transmissions** require **frequent clutch adjustments**, fluid changes, and eventual rebuilds (typically every **100,000 150,000 miles**).
- **Engines (especially the 318 inline-six)** are **thirsty for oil** and prone to **rod knock** if not maintained properly. The **360 V8** is more reliable but still needs **regular valve adjustments**.
- **Suspension components** (shocks, bushings, ball joints) wear out quickly in heavy-duty use and may need **frequent replacement**.
- **Brakes** (especially drums on older models) can be **weak under heavy loads** and require **upgrades** (e.g., power brakes, larger rotors).
2. **Poor Fuel Economy**
- Expect **8 12 MPG** in city driving and **10 15 MPG** on the highway **far worse than modern diesel or hybrid trucks**.
- **High fuel consumption** adds up over time, especially if used for long-distance towing.
3. **Outdated Safety and Comfort Features**
- **No modern safety tech** (no ABS, no airbags in most cases, poor visibility in some cab designs).
- **Rigid ride quality** these trucks are **not designed for highway comfort**; they re built for **work, not cruising**.
- **Heating and cooling systems** are **less efficient** than modern trucks, making them **less comfortable in extreme climates**.
4. **Rust and Structural Issues**
- Many **1980s 1991 Ram 50s** suffer from **frame rust**, especially in **snow belts, coastal areas, or high-humidity regions**.
- **Body panels** (especially on D150/D250) are **thin and prone to denting**, reducing resale value.
- **Fuel system issues** (leaking lines, carburetor problems) can be **annoying and costly** to fix.
5. **Limited Modern Conveniences**
- **No power steering** (on most manual-transmission models) steering is **heavy**, making long drives tiring.
- **No power brakes** (unless upgraded) braking requires **more effort**, especially when loaded.
- **No modern diagnostics** troubleshooting issues often requires **mechanical knowledge** rather than a scan tool.
6. **Parts and Labor Challenges**
- While **basic parts are cheap**, **specialized components** (e.g., rare transmissions, specific suspension parts) can be **hard to find**.
- **Finding a skilled mechanic** who knows these trucks well can be difficult, especially outside major cities.
- **Insurance costs** may be higher due to **lower safety ratings** and **higher risk of theft** (some models are targeted for parts).
7. **Driving Experience Limitations**
- **Manual transmissions** are **notoriously difficult to shift** in heavy loads (e.g., towing), requiring **strong legs and practice**.
- **No overdrive** (on most models) means **higher RPMs at highway speeds**, leading to **more engine wear**.
- **Poor fuel injection systems** (especially on carbureted models) can lead to **rough idling, stalling, or poor acceleration**.
8. **Environmental and Legal Considerations**
- **Emissions standards** may not meet modern regulations, leading to **restrictions in some areas** (e.g., smog checks, limited use in certain cities).
- **Noise and vibration** levels are **much higher** than modern trucks, which can be **annoying for daily driving**.
