Review MUSTANG Svt Heads Fresh Factory Cams fits COBRA 1999–2001

The **Ford Mustang RFY/RFYR3E6C064AB (1999-2001 SVT Cobra) High-Performance Head and Camshaft Kit** represents one of the most coveted and meticulously engineered upgrades for the iconic 4.6L Modular V8 found in the legendary **SVT Cobra** models. Designed exclusively for the **RFY (1999-2000) and RFYR3E6C064AB (2001) generation** of the SVT Cobra, this kit is a direct evolution of Ford s high-performance tuning program, crafted to maximize power, torque, and throttle response while maintaining the integrity of the engine s legendary reliability. The **Cobra heads** in this kit feature a **fully ported, high-flow design** with precision-machined intake and exhaust ports, optimized for aggressive airflow at high RPM while reducing turbulence and improving combustion efficiency. The **high-lift, long-duration camshafts** (typically around **280 duration at 0.050" lift**) are engineered to unleash the full potential of the **LS1-derived Modular V8**, delivering a dramatic shift in power delivery especially in the mid-to-high RPM range while preserving the Cobra s signature **smooth, linear torque curve**. When paired with supporting modifications like a **high-flow intake manifold, upgraded fuel injectors, and a tuned ECU**, this kit can propel the SVT Cobra from its stock **300-320 horsepower** range into the **400-450 horsepower** realm, all while retaining the engine s durability and the Cobra s legendary **4.9L Mustang heritage**. Whether you're chasing raw performance, a more aggressive exhaust note, or simply the unmistakable growl of a properly tuned Modular V8, this **RFY/RFYR3E6C064AB Cobra-specific head and cam kit** is a must-have for enthusiasts seeking to push their SVT Cobra beyond its factory limits without sacrificing the timeless character that defines this legendary muscle car.

**Pros and Cons of Buying a 1999-2001 Ford Mustang SVT Cobra (RFY/RFYR3E6C064AB) with Cobra Heads and Cams**

### **Pros**

1. **Performance Potential** The SVT Cobra is one of the most powerful stock Mustangs ever produced, with a naturally aspirated 5.0L V8 generating around **300 320 horsepower** (depending on modifications). The **Cobra Heads** (high-flow cylinder heads) and **performance cams** improve airflow and throttle response, making it a fun, track-capable machine.

2. **Strong Community & Aftermarket Support** The SVT Cobra has a dedicated fanbase, with extensive aftermarket parts available for upgrades, including **intake/exhaust systems, fueling solutions, suspension kits, and engine modifications**. Tuning options like **Holley, Edelbrock, or MSD** can further enhance performance.

3. **Classic Muscle Car Aesthetics** The **Cobra styling** (hood scoop, aggressive front bumper, and unique badging) gives it a distinct, high-performance look that stands out. The **RFY/RFYR3E6C064AB** designation (early 2000s) includes subtle refinements over the '99 model, such as improved interior materials and minor body updates.

4. **Reliability (With Proper Maintenance)** The **5.0L Coyote engine** (pre-2005) is known for durability if maintained correctly. Many Cobras with **oil changes, valve adjustments, and fuel system care** last well over **200,000 miles**. The **5-speed manual transmission** (common in early models) is robust, while the **4-speed automatic** (later models) can be upgraded with a **Tremec T-56** for better performance.

5. **Driving Experience** The **stiff chassis, limited-slip differential (LSD), and aggressive suspension tuning** make it a **fun, responsive driver s car**. The **manual transmission models** are particularly prized for their engaging shift feel.

6. **Investment Potential** Well-maintained SVT Cobras, especially **low-mileage examples with original parts**, have appreciated in value over the years. The **1999 2001 models** are considered **collectible**, though not as sought-after as the **2003 2004 Cobras**.

7. **Modular Upgrade Path** Unlike some older muscle cars, the **5.0L engine architecture** allows for **easy upgrades**, such as:

- **Big-block swaps** (e.g., **LS-based engines** for more power)

- **Turbocharging** (with proper fueling and cooling)

- **Suspension upgrades** (coilovers, sway bars, lower springs)

- **Braking improvements** (stainless steel rotors, caliper upgrades)

---

### **Cons**

1. **High Maintenance Costs** The **5.0L engine** requires **regular valve adjustments (every 30K 50K miles)**, **fuel system cleaning**, and **cooling system maintenance**. **Oil leaks** (valve cover, oil pan, rear main seal) are common if not addressed early. **Transmission issues** (especially in automatics) can be costly to repair.

2. **Fuel Economy** The **naturally aspirated 5.0L** gets **around 12 15 MPG in the city and 18 22 MPG on the highway**, making it **expensive to drive** compared to modern cars. **Turbocharging or big-block swaps** will only worsen this.

3. **Rust & Body Issues** Many **1999 2001 Mustangs** suffer from **frame rust**, especially in **snow-belt regions**. The **hood, rocker panels, and wheel wells** are also prone to corrosion. A **thorough inspection** is essential before purchase.

4. **Originality vs. Modifications** Some buyers prefer **stock Cobras**, but many are **heavily modified** (turbocharged, nitrous, custom intakes/exhausts). If you want a **stock or near-stock example**, you may pay a premium, while **project cars** require significant investment.

5. **Parts & Labor Costs** While parts are available, **specialty items** (e.g., **Cobra-specific suspension components, rare interior parts**) can be expensive. **Labor costs** for engine work or transmission rebuilds can add up quickly.

6. **Driving Limitations** The **stock suspension is stiff and uncomfortable** for daily driving. **Bump steering** and **poor ride quality** can make long trips or city commuting **less enjoyable** unless heavily modified.

7. **Depreciation Risk** While **low-mileage, well-documented Cobras hold value**, **high-mileage or neglected examples depreciate quickly**. If you plan to **modify it heavily**, resale value may not recover original costs.

8. **Legal & Insurance Considerations** Some **high-performance modifications** (turbocharging, nitrous, widebody kits) may **void warranties** or **increase insurance costs**. Check local **homologation laws** if you plan aggressive upgrades.

### **Conclusion & Recommendation**

The **1999 2001 Ford Mustang SVT Cobra (RFY/RFYR3E6C064AB) with Cobra Heads and cams** is a **fantastic choice** if you:

- **Love classic muscle cars** and enjoy **project cars**.

- **Prioritize performance and driving fun** over daily practicality.

- **Have mechanical experience** or are willing to **invest in maintenance**.

- **Plan to modify it** (turbo, big-block, suspension upgrades).

- **Appreciate the community and aftermarket support**.

However, it is **not the best choice** if you:

- **Need a reliable, low-maintenance daily driver**.

- **Can t afford high fuel costs or unexpected repairs**.

- **Prefer a fully stock or low-mileage example** (without a budget for restoration).

- **Live in an area with harsh winters** (rust and corrosion will be a major concern).

#### **Final Recommendation:**

- **Buy it if:** You re **passionate about Mustangs**, have **budgeted for maintenance/mods**, and **enjoy the process of building a high-performance car**. Look for a **low-mileage example (under 100K miles) with a clean service history**, preferably with **original Cobra Heads and cams** (though some wear is normal).

- **Avoid it if:** You want a **plug-and-play, low-cost classic** or a **modern, efficient vehicle**. Consider alternatives like a **restomod Mustang (2005 with modern tech) or a well-maintained '95 '98 Cobra** if you prefer something slightly older but more reliable.

**Best Approach:**

- **Inspect thoroughly** (engine bay, transmission, frame, suspension).

- **Get a pre-purchase inspection** from a **Mustang specialist**.

- **Budget for immediate fixes** (rust repairs, oil leaks, transmission work).

- **Join Mustang forums** (e.g., **Mustang.org, SVTForums**) for advice on specific models.

If you re **serious about the project**, the **1999 2001 SVT Cobra** can be an **incredibly rewarding** and **highly enjoyable** build just be prepared for the **work and cost** that comes with it.
