Review CHRYSLER Sport Script Plymouth Mopar fits SUBURBAN FURY 1970–1977

The **Chrysler 3446766 Sport Suburban Script** is a legendary, high-performance engine from the golden era of American muscle, meticulously crafted for the 1970 1977 Plymouth Fury and its close cousin, the Dodge Charger. This iconic **340-cubic-inch (5.6-liter) V8**, often referred to as the **"340 Script"** or **"340 Mopar,"** stands as a testament to Chrysler s bold engineering and the unbridled spirit of the muscle car era. Designed to deliver raw, unfiltered power with a distinctive, aggressive exhaust note, this engine was originally introduced in 1966 as a high-performance variant of the proven **340 LA** block, featuring a unique **dual-plane intake manifold** with a **script-style valve cover** a signature detail that gives it its name. The **3446766** designation refers to its specific casting and configuration, distinguishing it from other 340 variants, including the **340 Magnum** and **340 Hemi** (which featured a different valve cover design). Under the hood, this engine boasts a **compression ratio of 10.5:1**, paired with a **four-barrel Carter AFB carburetor**, producing a staggering **275 300 horsepower** (depending on year and tuning) and **340 lb-ft of torque**, enough to propel a Fury or Charger from 0-60 mph in under **7 seconds** on the street or dominate the drag strip. The **340 Script** was particularly favored by enthusiasts for its **durability, smooth power delivery, and classic muscle car sound**, making it a staple in both show cars and restoration projects. Its **cast-iron block and head**, **hydraulic lifters**, and **solid lifter alternatives** (commonly aftermarket) ensure reliability, while its **forged crankshaft and connecting rods** (in later years) reinforce its reputation as a workhorse. Whether installed in a **1970 1977 Plymouth Fury** complete with its bold, angular styling, **quad headlights, and aggressive front grille** or a **Dodge Charger**, this engine transforms a classic muscle car into a **high-performance legend**, blending raw power with timeless American craftsmanship. For collectors and restorers, the **3446766 Sport Suburban Script** isn t just an engine it s a piece of automotive history, embodying the unapologetic, high-octane ethos of the muscle car era.

### Pros and Cons of Buying a 1970 1977 Chrysler 3446766 Sport Suburban (Script) or Plymouth Fury (Mopar)

#### **Pros**

**1. Classic Muscle Car Appeal**

These vehicles represent a golden era of American muscle cars, particularly the late 1960s and early 1970s. The Chrysler 3446766 Sport Suburban (often a modified or high-performance version of the Chrysler Cordoba or New Yorker) and the Plymouth Fury (especially with the 440 or 426 Hemi engine) are highly sought-after by enthusiasts. Their bold styling, powerful engines, and cultural significance make them desirable for collectors and restorers.

**2. Strong Engine Options**

- The **Chrysler 3446766** (often a 440 cubic inch or 426 Hemi engine) was a powerhouse in its day, capable of producing **375 425 horsepower** (pre-1971) or **275 300 hp** (post-1971 due to emissions regulations). These engines, when properly maintained, can still deliver impressive performance, especially if modified.

- The **Plymouth Fury** (especially the **440 Six-Pack** or **426 Hemi**) was a dominant force in drag racing and street performance. The 426 Hemi, in particular, is one of the most iconic engines in American automotive history, known for its raw power and reliability when kept in good condition.

**3. Durability and Build Quality**

Chrysler and Plymouth vehicles from this era were built with solid construction. The **unibody chassis** (on most models) and **heavy-duty suspension** (especially on the Fury) were designed for performance and comfort. Many of these cars, when well-maintained, can last for decades with proper care.

**4. Customization Potential**

These vehicles are popular among hot rod and custom car builders. The **Chrysler 3446766** (often a luxury-based platform) can be transformed into a sleek, modern muscle car, while the **Plymouth Fury** (especially the **GTX or Satellite**) offers a more aggressive, performance-oriented base. Swapping in modern engines, suspension upgrades, or restyling the bodywork is a common and rewarding project.

**5. Nostalgia and Investment Value**

For collectors, these cars hold **sentimental and financial value**. Well-preserved examples, especially those with **original engines, interiors, or rare options**, can appreciate in value over time. The **Plymouth Fury 426 Hemi** and **Chrysler 3446766** (especially in showroom condition) are particularly valuable in the classic car market.

**6. Availability of Parts**

While some parts may be harder to find than on modern vehicles, the **aftermarket support** for these cars is strong. Companies like **Mopar (Chrysler s parts division), Holley, Edelbrock, and various custom shops** produce aftermarket components, making repairs and modifications easier than on some other vintage cars.

**7. Driving Experience**

For those who appreciate **raw power and vintage handling**, these cars offer an exciting driving experience. The **426 Hemi** in particular delivers a **deep, growling exhaust note** and **brutal acceleration**, while the **440 Six-Pack** provides a smooth yet powerful ride. The **Sport Suburban** (a luxury-based platform) offers a more refined, high-performance cruiser experience.

#### **Cons**

**1. High Maintenance Costs**

Vintage muscle cars require **significant upkeep**, especially if they have high-mileage engines or rusted frames.

- **Engines:** The **426 Hemi** and **440 Six-Pack** are legendary but **complex and expensive to rebuild**. Modern fuel systems, ignition components, and emissions controls may not be compatible without modifications.

- **Transmissions:** Many of these cars came with **TorqueFlite automatic transmissions**, which can be finicky and require **fluid changes and synchronizer adjustments**.

- **Suspension & Steering:** Original **leaf springs, shocks, and steering components** wear out over time and may need replacement.

- **Electrical Systems:** Older wiring harnesses and components can fail, requiring **restoration or replacement**.

**2. Rust and Frame Issues**

Many vehicles from this era suffer from **frame rust**, particularly in **salt-affected regions**. A **full frame-off rust repair** can cost **$3,000 $10,000 **, depending on the extent of corrosion. Even if the frame is sound, **body panels** (especially on the Fury) may need replacement due to rust or dents.

**3. Emissions and Modern Compliance**

Modern **emissions laws** make it difficult to run these cars legally in many areas without modifications.

- **Smog Checks:** Many states require **OBD-II compliant** systems, which may require **aftermarket tuners or emissions control devices**.

- **Fuel Injectors vs. Carburetors:** Some modern fuel pumps and injectors are incompatible with **Holley or Carter carburetors**, requiring **fuel system upgrades**.

- **Exhaust Restrictions:** Some areas have **noise ordinances** that may limit the **deep, throaty exhaust notes** these engines produce.

**4. Insurance Costs**

Insuring a **vintage muscle car** can be **expensive**, especially if it s a **high-performance or high-value model**. Some insurers may classify them as **"high-risk"** due to their age and power, leading to **higher premiums**. **Agreed-value policies** (which pay the car s appraised value in case of total loss) are often required but can be costly.

**5. Fuel Economy**

These cars were not designed for efficiency. The **426 Hemi** gets **around 8 10 MPG**, while the **440 Six-Pack** manages **10 12 MPG**. Modern fuel prices make long-distance driving **impractical and expensive**.

**6. Limited Modern Comforts**

- **Seating:** Original interiors (especially in the **Sport Suburban**) may be **less comfortable** than modern vehicles, with **hard seats and limited adjustability**.

- **Safety:** **No modern airbags, stability control, or advanced braking systems** mean these cars are **less safe** in a collision.

- **Technology:** **No Bluetooth, USB ports, or modern infotainment** driving is a **more analog experience**.

**7. Project Car Challenges**

If the car is **not already restored**, it may require **extensive work** to bring it to a drivable or show-ready condition. This includes:

- **Engine rebuilds or swaps** (if the original is beyond repair).

- **Transmission and drivetrain work** (differentials, axles, and universal joints wear out).

- **Electrical system restoration** (starter, alternator, wiring, and gauges).

- **Bodywork and paint** (rust repair, panel replacement, and refinishing).

- **Suspension and steering overhauls** (shocks, bushings, and tie rods).

**8. Limited Modern Parts Compatibility**

While aftermarket parts exist, some **modern components (alternators, starters, sensors, etc.)** may not fit perfectly without modifications. **OEM parts** (from Mopar or other suppliers) can be **expensive and hard to find**.

**9. Driving Limitations**

- **Size and Weight:** These cars are **heavy** (especially the Fury), making them **less nimble** than modern sports cars.

- **Braking:** Original **drum brakes** (on some models) are **less effective** than modern disc brake systems.

- **Tire and Suspension Wear:** The **large, heavy tires** and **stiff suspension** can lead to **uneven tire wear** and **poor handling** over time.

**10. Market Saturation**

The **classic muscle car market is competitive**, meaning **prices for well-preserved examples can be high**. Buyers may need to **compete with collectors and investors**, driving up costs. Additionally, **fake or poorly restored cars** flood the market, making it **harder to find a genuinely solid example**.

---

### **Conclusion**

Buying a **1970 1977 Chrysler 3446766 Sport Suburban (Script) or Plymouth Fury (Mopar)** is a **rewarding but challenging** endeavor. These cars offer **unmatched nostalgia, power, and customization potential**, making them **ideal for enthusiasts who enjoy working on projects and appreciate vintage American muscle**. However, they also come with **high maintenance costs, rust concerns, emissions challenges, and insurance expenses** that can make ownership **financially demanding**.

If you are **passionate about classic cars, willing to invest time and money in restoration, and enjoy the hands-on aspect of automotive repair**, one of these vehicles could be a **fantastic addition to your collection**. On the other hand, if you **prioritize convenience, modern safety, and low maintenance**, these cars may not be the best choice.
