### **Pros and Cons of Buying a Mopar 4397675 2.2L NOS (1984 1986 Plymouth/Dodge/Chrysler) Connecting Rod Set**

#### **Pros**

1. **High Performance Potential**

The 2.2L inline-four engine (OM6) was designed for reliability and efficiency, but with proper modifications, it can produce respectable power. A NOS connecting rod set ensures structural integrity, allowing for increased compression ratios, forced induction, or higher RPM operation without catastrophic failure.

2. **Rare and Collectible**

NOS (New Old Stock) parts are highly sought after by enthusiasts, especially for classic Chrysler engines. The 4397675 rod set is a genuine factory component, making it a desirable addition for restoration or high-performance builds.

3. **Compatibility with Aftermarket Support**

The 2.2L engine has a strong aftermarket following, with availability of performance parts like headers, turbo kits, fuel systems, and ECU tuning. A NOS rod set ensures that the engine can handle these upgrades without compromising safety.

4. **Long-Term Reliability**

Mopar NOS parts are built to original specifications, often with higher-quality materials than modern aftermarket alternatives. This can extend the engine s lifespan, especially if the rest of the build is maintained properly.

5. **Aesthetic and Historical Value**

For collectors and restorers, NOS parts add authenticity to a project. The 2.2L engine was used in popular muscle cars (e.g., 1984 1986 Dodge Omni 024, Plymouth Horizon GTX, Chrysler TC3), making it a nostalgic choice for enthusiasts.

6. **Potential for Engine Rebuilding**

If the engine is already in need of a rebuild, NOS rods provide a premium option over OEM or aftermarket replacements. They can be paired with other NOS components (crankshaft, pistons, bearings) for a fully restored factory-spec engine.

---

#### **Cons**

1. **High Cost**

NOS parts are significantly more expensive than OEM or aftermarket alternatives. The 4397675 rod set will likely cost **$200 $400 **, depending on availability and condition. This can be a major investment for a project car.

2. **Limited Availability**

NOS inventory is finite, and popular parts (especially for older Chrysler engines) can sell out quickly. Prices may rise if demand outstrips supply, making it a speculative purchase.

3. **Not Always Necessary for Stock Applications**

If the engine is being used in a stock or lightly modified car, a NOS rod set may be overkill. Modern aftermarket rods (e.g., JE, Scat, or even OEM replacements) can be just as reliable for stock or mild performance builds at a fraction of the cost.

4. **Potential for Counterfeit or Mismatched Parts**

The NOS market has seen instances of counterfeit or mislabeled parts. Buyers must verify authenticity through reputable sellers (e.g., Mopar, eBay verified, or trusted collectors) to avoid receiving fakes.

5. **Installation Complexity**

Rebuilding an engine with NOS rods requires mechanical skill. If the engine is being rebuilt from scratch, labor costs will add up, and mistakes (e.g., improper gap, torque specs) can void the benefits of NOS parts.

6. **Depreciation Risk**

While NOS parts appreciate in value for collectors, they may not hold their worth if the engine is modified beyond stock. If the goal is purely performance, the investment may not yield long-term financial returns.

---

### **Ending Conclusion**

The **Mopar 4397675 NOS connecting rod set** is an excellent choice for enthusiasts who prioritize **authenticity, long-term reliability, and high-performance potential** in their 2.2L engine project. It is particularly valuable for **restorers, collectors, or those planning significant modifications** (turbocharging, forced induction, or high-RPM applications). However, it is **not a cost-effective solution** for casual drivers or those building a stock or mildly modified engine.

- **Budget** (NOS parts are expensive; weigh against aftermarket alternatives).

- **Project Goals** (restoration vs. performance; stock vs. modified).

- **Availability** (ensure the part is genuine and not counterfeit).

- **Long-Term Plans** (if the engine will be preserved as a collector s item, NOS justifies the cost; if it s a disposable performance build, cheaper options may suffice).

---

### **Recommendation**

- You are restoring a classic Chrysler/Plymouth/Dodge with the 2.2L engine and want factory-spec components.

- You plan to **turbocharge, supercharge, or significantly modify** the engine and need the strongest possible internals.

- You are a **collector** who values NOS parts for their historical and resale value.

- You have **verified the authenticity** from a trusted source and are prepared for the higher cost.

- You are on a **tight budget** and the engine will remain stock or lightly modified.

- You prioritize **cost efficiency** over NOS authenticity.

- You are rebuilding the engine for **performance only** (not preservation) and can find equally strong aftermarket rods (e.g., JE 1000 series, Scat 4340 steel).

For most **performance-focused builds**, a **high-quality aftermarket rod set** (e.g., **Scat 4340, JE 1000, or ARP**) may offer a better **cost-to-performance ratio** while still providing reliability. However, if **authenticity and long-term value** are the priorities, the NOS rod set is a worthwhile investment.
