### Pros and Cons of Buying a Classic Mopar E-Body Block (1966 1972) with a Big Motor Mount Swap (B/RB)

#### **Pros**

1. **Strong Heritage and Performance Legacy**

The 383, 400, and 440 cubic inch Mopar V8 engines from this era are legendary for their durability, power potential, and aftermarket support. These engines were designed for high-performance applications, including muscle cars, drag racing, and street machines. A well-maintained example can still deliver impressive power with relatively modern modifications.

2. **Highly Customizable**

The E-body block (383/400/440) is one of the most popular Mopar engines for swapping and building. It benefits from decades of aftermarket parts, including:

- **Big Block Swap Potential:** The E-body block can be swapped into a variety of chassis (Dodge Challenger, Charger, Barracuda, etc.), making it versatile for restomods or modern builds.

- **Big Motor Mounts (B/RB):** These mounts are designed to handle more power and torque than stock mounts, reducing stress on the engine bay and improving reliability. They re a common upgrade for high-performance applications.

- **Forced Induction Potential:** The block can handle nitrous oxide, turbocharging, or supercharging with proper reinforcement, making it a great platform for modern power.

- **Crankshaft and Rod Options:** Aftermarket cranks (like Eagle, Crane, or Scat), forged rods (ARP, JE, or Eagle), and pistons (Wastegate, JE, or Mahle) are widely available to build a high-stress engine.

3. **Parts Availability and Community Support**

- **Stock and Aftermarket Parts:** Spare parts for these engines are still widely available, including gaskets, seals, intake manifolds, and carburetors (Holley, Edelbrock, or Carter).

- **Tuning and Diagnostics:** Modern tuning tools (like Haltech, Link, or AEM) can optimize fuel delivery and ignition for these engines, even with modern ECUs.

- **Restoration and Rebuilding:** Many shops specialize in Mopar engines, and resources like YouTube tutorials, forums (like Hemmings, Mopar Muscle, or E-Body Forum), and books make rebuilding accessible.

4. **Potential for High Power Output**

With the right modifications, these engines can produce **500 800 horsepower** (or more with aggressive builds). Examples include:

- **Stock-based builds:** 440 Six-Pack with a big cam, headers, and a carb (e.g., 450 500 HP).

- **Turbocharged builds:** 600 800 HP with a turbo kit (e.g., Garrett, BorgWarner) and supporting mods.

- **Supercharged builds:** 500 700 HP with a blower (e.g., Edelbrock, Supercharger Systems).

- **Nitrous-assisted builds:** Quick power boosts for drag racing or street applications.

5. **Nostalgia and Collectibility**

For enthusiasts who appreciate the muscle car era, owning a classic Mopar engine especially in an E-body is a nostalgic and rewarding experience. Restored examples can also appreciate in value, particularly if they re part of a complete classic car.

6. **Reliability with Proper Maintenance**

While these engines are known for their durability, they require **regular maintenance** (valve adjustments, oil changes, gasket replacements) to avoid common issues like rod knock, oil leaks, or head gasket failure. When properly cared for, they can last **200,000 miles** or more.

---

#### **Cons**

1. **Potential for Hidden Issues**

- **Rod Knock and Wear:** The 383/400/440 blocks are prone to rod knock if the engine is neglected. Always check for:

- **Rod bearing wear** (scoring, pitting).

- **Crankshaft journals** for wear or cracks.

- **Connecting rod bolts** for stretch or damage.

- **Head Gasket Failure:** Common in high-mileage examples, leading to coolant loss, oil dilution, or catastrophic failure. Always inspect for warped heads or cracked water passages.

- **Camshaft Wear:** Older cams can wear out, causing rough idle or poor performance. Replacing the cam and lifters is often necessary.

- **Oil Leaks:** Gaskets (oil pan, valve cover, rear main seal) degrade over time and may require replacement.

2. **Cost of Restoration and Modifications**

- **Rebuilding a Long-Term Neglected Engine:** If the engine has been sitting for decades, rebuilding it from scratch can cost **$3,000 $8,000 **, depending on the extent of damage and parts needed.

- **Modernization Costs:** Swapping into a modern chassis (e.g., Challenger) may require:

- **Exhaust and intake upgrades** (cat-back systems, headers, modern intakes).

- **Fuel system upgrades** (fuel pump, injectors, fuel rail, ECU).

- **Drivetrain reinforcement** (differential, driveshaft, transmission).

- **Big Motor Mounts (B/RB):** While these are a worthwhile upgrade, they re not cheap (**$200 $500 per set**) and may require additional modifications (e.g., firewall reinforcement, sway bar deletion).

3. **Fuel and Emissions Challenges**

- **Modern Fuel Standards:** These engines were designed for **87 91 octane fuel**, but modern fuel is often lower in octane. Running **93 octane** can help prevent detonation, especially with forced induction.

- **Emissions Compliance:** If you plan to drive the car legally on the road, you ll need:

- **Modern emissions components** (catalytic converters, OBD-II ECU, EVAP system).

- **Smog checks** in some states, which can be difficult with high-performance mods.

- **Alternate Fuel Options:** If you want to avoid emissions issues, consider **E85 flex-fuel** (requires a compatible ECU) or **nitrous-only** setups.

4. **Driving Experience Limitations**

- **Vibration and Roughness:** Stock E-body engines can be **vibrant and rough** at idle, especially with stock cams. Modern cams or harmonic balancer upgrades can help.

- **Transmission Matching:** Mating these engines with modern transmissions (e.g., Tremec T56 in a Challenger) requires careful tuning to avoid jerkiness or poor shifting.

- **Weight and Handling:** Big-block Mopar engines are **heavy** (600 700 lbs with accessories), which can affect handling in lighter chassis (e.g., early E-bodies). Big motor mounts help, but sway bar deletion or coilover suspension may be needed for optimal performance.

5. **Time-Consuming Projects**

- **Restoration Effort:** If you re not mechanically inclined, a classic Mopar engine project can be **extremely time-consuming**. Even a "running" example may need:

- **Full disassembly and inspection.**

- **Gasket replacement (heads, oil pan, valve cover).**

- **Camshaft and lifter replacement.**

- **Rod bolt torque sequence and inspection.**

- **Swapping into a Modern Chassis:** If you re building a restomod, expect **hundreds of hours** of work for:

- **Engine removal/installation.**

- **Exhaust and intake routing.**

- **Wiring harness and ECU setup.**

- **Drivetrain and suspension tuning.**

6. **Reliability Risks with Aggressive Mods**

- **Forced Induction Risks:** Turbocharging or supercharging these engines can be **brutal** if not done correctly. Common failure points include:

- **Rod bolts** (must be ARP or equivalent).

- **Connecting rods** (must be forged).

- **Crankshaft** (must be strong enough for boost).

- **Fuel system** (must match power output).

- **Nitrous Oxide Risks:** While nitrous is a quick power boost, it can cause **catastrophic failure** if the engine isn t properly supported (e.g., weak rods, low octane fuel).

7. **Market Saturation and Value Depreciation**

- **Common Engine:** The 383/400/440 is **not rare**, so finding a "perfect" example can be competitive. Prices for complete cars or engines can fluctuate based on demand.

- **Depreciation Risk:** If you re building a project car, the value may not increase as much as a fully restored classic. However, if you re restoring a complete E-body (e.g., 1968 Charger), it can appreciate significantly.

---

### **Ending Conclusion**

Buying a classic Mopar E-body block (1966 1972) with a big motor mount swap is a **fantastic choice for enthusiasts** who want a **highly customizable, powerful, and rewarding** project. These engines offer **unmatched potential for power
