Review FORD 7.3l Engine Motor Crankshaft Crank Shaft Oem fits F-350 2023–2024

The **Ford LC3Z630A 2023 2024 F-350 7.3L Power Stroke Turbo Diesel Engine** represents the pinnacle of modern heavy-duty performance, engineered to deliver relentless power, durability, and efficiency for the most demanding towing, hauling, and overlanding applications. At the heart of this legendary engine lies the **7.3L V8 turbocharged diesel crankshaft**, a precision-forged masterpiece designed to withstand the harshest conditions while maintaining seamless operation under extreme loads. Crafted from high-grade **chromoly steel**, this crankshaft features a **fully counterweighted design** with **five main journals** and **eight crankpins**, ensuring optimal balance and reduced vibration even at high RPMs, which is critical for maintaining smooth power delivery in a vehicle capable of producing over **475 horsepower and 1,050 lb-ft of torque**. The crankshaft s **hardened and ground surfaces**, along with **precision-machined oil grooves**, enhance lubrication and longevity, allowing it to endure the relentless demands of continuous heavy-duty use without compromising performance. Whether hauling a massive load, towing a heavy trailer, or conquering rugged terrain, this crankshaft is a testament to Ford s commitment to building an engine that doesn t just meet expectations it redefines them. Built to Ford s stringent **Power Stroke standards**, this component is a key element in the engine s ability to deliver **unmatched torque on demand**, making it ideal for applications where raw power and reliability are non-negotiable. The **2023 2024 model iteration** incorporates the latest refinements in materials and manufacturing, ensuring even greater resistance to wear and fatigue, while the **integrated turbocharging system** optimizes airflow for peak efficiency, reducing emissions and improving fuel economy without sacrificing power. For those who demand the best in heavy-duty performance, the **LC3Z630A crankshaft** is not just a part it s the backbone of an engine built to last a lifetime of tough miles.

### **Pros and Cons of Buying a 2023-2024 Ford F-350 with a 7.3L Power Stroke Engine (LC3Z6303A Crankshaft)**

#### **Pros**

1. **Proven Reliability and Durability**

The 7.3L Power Stroke engine has been in production since 2003 and is widely regarded as one of the most robust diesel engines in Ford s lineup. It is known for its longevity, especially when properly maintained. Many units exceed 500,000 miles with regular upkeep.

2. **High Torque and Towing Capacity**

The 7.3L produces **450 lb-ft of torque**, making it one of the strongest engines in its class. This translates to excellent towing and hauling performance, ideal for heavy-duty applications like large trailers, boats, or construction equipment. The F-350 Super Duty can tow up to **20,000 lbs** with the right setup.

3. **Simplicity and Ease of Maintenance**

Compared to newer turbocharged diesel engines, the 7.3L is a **naturally aspirated** design, which means fewer complex components like turbochargers, EGR systems, or DPFs (Diesel Particulate Filters). This reduces long-term maintenance costs and simplifies repairs. Common issues like turbo failure or DPF clogging are not a concern.

4. **Strong Aftermarket Support**

The 7.3L has been around for nearly two decades, meaning there is an extensive aftermarket for parts, upgrades, and modifications. Performance chips, exhaust systems, and fuel system upgrades are readily available, allowing owners to customize their trucks for better power or efficiency.

5. **Lower Fuel Consumption Compared to Turbocharged Diesels**

While not the most fuel-efficient engine, the 7.3L typically consumes **around 12-15 MPG** in mixed driving, which is better than some turbocharged diesels that may average **10-12 MPG** due to turbo lag and aftertreatment systems.

6. **Resale Value and Market Demand**

The 7.3L remains highly sought after in the used market, especially for those who prioritize simplicity and reliability over the latest emissions technology. This can lead to better resale value compared to newer, less proven engines.

7. **No Emissions-Related Concerns**

Unlike newer diesel engines that rely on **EGR coolers, DPFs, or SCR systems**, the 7.3L does not suffer from common emissions-related failures (e.g., clogged DPFs, EGR cooler leaks). This makes it a more "future-proof" choice for those who want to avoid costly emissions-related repairs.

8. **Lower Initial Cost (Compared to Turbocharged Models)**

The 7.3L is often priced lower than the newer **7.3L turbocharged** or **6.7L Power Stroke** models, making it an attractive option for buyers on a budget who still want a heavy-duty diesel.

---

#### **Cons**

1. **Lower Fuel Efficiency Than Turbocharged Diesels**

While the 7.3L is more efficient than many naturally aspirated gas engines, it still lags behind turbocharged diesel competitors (e.g., the **6.7L Power Stroke**) in fuel economy. Expect **12-15 MPG** in city driving, which is decent but not exceptional for a heavy-duty truck.

2. **No Turbocharger Means Less Power (Relative to Modern Engines)**

The 7.3L produces **less horsepower (300-320 HP)** compared to newer turbocharged diesels (e.g., the **6.7L Power Stroke with 440 HP**). If raw power is a priority, a turbocharged engine may be more appealing.

3. **Higher Noise and Vibration Levels**

Naturally aspirated diesel engines tend to be **louder and more vibration-prone** than turbocharged counterparts. The 7.3L has a distinctive **rumbling exhaust note**, which some may find enjoyable, while others prefer the smoother operation of turbocharged engines.

4. **Limited Modern Technology and Features**

The 7.3L lacks some of the advanced diagnostics and emissions controls found in newer engines. While this reduces complexity, it also means fewer **OBD-II trouble codes** and less integration with modern Ford tech (e.g., SYNC 4, advanced driver aids).

5. **Potential for Carbon Buildup in Intake Manifold**

Naturally aspirated diesels are prone to **carbon deposits** in the intake ports over time, which can reduce performance. Regular **intake cleaning** is recommended to maintain optimal airflow.

6. **Higher Maintenance Costs for Some Components**

While the engine itself is simple, **transmissions (especially the 6R140/6R150) and drivelines** can be expensive to repair if they fail. The 7.3L is paired with **heavy-duty transmissions**, but these are not immune to wear over extreme towing loads.

7. **Less Common in Newer Model Years (2023-2024)**

- **Limited availability** of new units (if any) in 2023-2024.

- **Higher demand for used examples**, which may drive up prices.

- **Potential for parts shortages** as production winds down.

8. **Emissions Compliance (EPA 2010 Standards)**

The 7.3L in 2023-2024 models is **EPA 2010 compliant**, meaning it includes some emissions controls (e.g., **EGR system, DPF-like aftertreatment**). While not as complex as a turbocharged diesel, these systems may still require occasional maintenance.

---

### **Conclusion**

- **Reliability and longevity** over cutting-edge technology.

- **Simplicity and low maintenance** (no turbo, DPF, or complex emissions systems).

- **Heavy-duty towing and hauling** without the risk of turbo-related failures.

- **Strong aftermarket support** and proven durability.

- **Higher fuel efficiency** (turbocharged diesels get better MPG).

- **More power** (turbocharged engines produce significantly more HP).

- **Modern Ford tech integration** (SYNC 4, advanced diagnostics).

- **A newer engine with fewer miles**, a turbocharged 6.7L or 7.3L may be preferable.

### **Recommendation**

- You need a **workhorse truck** for extreme towing/hauling.

- You prefer **simplicity and lower long-term maintenance costs**.

- You want an **engine that will last 500,000 miles** with proper care.

- You re okay with **slightly lower fuel economy** and a **louder exhaust note**.

- You want **maximum fuel efficiency** (turbocharged diesels are better).

- You prioritize **modern tech and diagnostics** over legacy reliability.

- You plan to **drive mostly in city traffic** (higher RPMs can accelerate wear).

- You can find a **well-maintained turbocharged 6.7L or 7.3L** at a similar price with better power.

The **7.3L is the best choice for those who want a no-nonsense, bulletproof diesel truck** especially if you re buying used or in a market where turbocharged engines are scarce. If you can afford a **turbocharged 6.7L or 7.3L**, it may offer better performance and efficiency, but the 7.3L remains a **time-tested, low-risk option** for heavy-duty work.
