The **Ford 6.5L (390 cu. in.) Cleveland V8 (6579M2MP-SBF) Performance Engine**, commonly found in the iconic **Mustang II (F-100) from 1965 to 1979**, represents a legendary powerplant that blends raw muscle with timeless American engineering. This high-performance variant of Ford s legendary **Cleveland V8** architecture was meticulously crafted for those seeking a balance between brute force and refined drivability, making it a standout choice for enthusiasts and restorers alike. The **32-valve, crossflow-head design** (with a single-plane crankshaft) delivers an unmistakable growl and a torque curve that s both immediate and relentless, whether paired with the **289, 302, or 351W** displacement iterations each offering a distinct character while adhering to the same mechanical DNA. The **SBF (Special Big Ford) designation** signifies a high-performance build, featuring forged internals, a reinforced block, and a **high-lift camshaft** that maximizes airflow through the **4.225-inch intake and 1.60-inch exhaust valves**, ensuring a throaty, high-revving exhaust note that s as satisfying as it is iconic. This engine was originally designed for the **1970 1971 Boss 351**, but its adaptability made it a staple in **Mustang II (F-100) applications**, where it could be tuned for everything from **street cruising to drag strip domination**. The **351W (Windsor-based Cleveland)** variant, in particular, stands out for its **cast-iron block with a forged crankshaft, connecting rods, and pistons**, while the **302 and 289 versions** offer lighter, more manageable alternatives without sacrificing performance. Whether restored to its original **1960s muscle-car glory** or modified for modern high-performance use, this engine embodies the spirit of **Ford s golden era of V8 power** a perfect blend of heritage, reliability, and unbridled enthusiasm.

#### **Cons**
1. **Aging Mechanical Components**
- **Original suspension** (leaf springs, solid axles) can be stiff and uncomfortable for modern driving.
- **Braking systems** (drums or weak discs) may require upgrades for safety.
- **Transmission wear** Original automatic transmissions (e.g., C4) can be unreliable without rebuilds.
- **Fuel system issues** Carburetors (e.g., Holley 4150) require tuning and maintenance to prevent stalling or poor performance.
2. **Reliability Concerns**
- **Original engines** (especially 289s) can be prone to **rod bearing failure, oil leaks, or camshaft issues** if not properly maintained.
- **Electrical systems** (alternators, wiring) may need upgrades for modern accessories.
- **Rust** Many older Mustangs suffer from **floor pans, rocker panels, and frame rust**, requiring extensive repairs.
3. **High Maintenance Costs**
- **Regular upkeep** (valve adjustments, ignition timing, carburetor tuning) is necessary to keep performance engines running smoothly.
- **Replacement parts** (e.g., springs, bushings, seals) can be expensive, especially for rare or discontinued components.
- **Labor costs** Some repairs (e.g., transmission rebuilds, engine swaps) require specialized mechanics.
4. **Fuel Economy Limitations**
- **Naturally aspirated V8s** average **12 15 MPG** in city driving, making them impractical for daily use over long distances.
- **High-performance builds** (especially with forced induction) can drop efficiency further.
5. **Insurance and Registration Challenges**
- **Classic car insurance** can be costly, especially for high-performance or modified examples.
- **Emissions compliance** (in some states) may require modifications to meet modern standards.
- **Title issues** Some older Mustangs may have **salvage titles, flood damage, or missing parts**, complicating ownership.
6. **Driving Comfort and Modern Safety**
- **Rigid ride quality** Original suspensions are harsh compared to modern suspensions.
- **Lack of modern safety features** (no ABS, stability control, or advanced airbags).
- **Visibility** Some body styles (e.g., early F-100s) have limited rearward and side visibility.
7. **Market Saturation**
- **High competition** Many Mustangs are available, making it difficult to find a **rare, well-documented, or low-mileage example**.
- **Overpriced "restored" examples** Some sellers inflate prices for cosmetic restorations without proper mechanical attention.
8. **Storage and Transportation**
- **Classic cars require careful storage** (garage, climate-controlled) to prevent rust and damage.
- **Towing a Mustang** (especially long-wheelbase models) can be challenging and expensive.

### **Ending Conclusion**
Buying a **1965 1979 Ford Mustang (F-100 series, IFS, 289/302/351 HP, CPP/SBF)** is a **fantastic choice for enthusiasts** who appreciate **performance, nostalgia, and customization potential**. The platform offers **proven power, strong aftermarket support, and endless modification possibilities**, making it ideal for **weekend drivers, track enthusiasts, or restomod projects**.
However, **ownership comes with challenges** **high maintenance costs, reliability concerns, and practical limitations** (fuel economy, comfort, safety) must be carefully considered. If you are **willing to invest time and money in upkeep**, a well-chosen Mustang can be an **incredible driving experience** and a **valuable long-term project**.
For **daily drivers**, a **modern muscle car or a well-maintained classic** (like a **Mustang GT or a restored 1967 model**) may be more practical. But for **purists, racers, and collectors**, the **F-100 series remains one of the best muscle car platforms** to own.

### **Recommendation**
1. **If you want a project car:**- **Target a 302 or 351 Cleveland engine** (more reliable than a 289).
- **Look for a well-documented example** with **service records** (especially for valve adjustments, ignition, and fuel system).
- **Budget for a full restoration or rebuild** (expect **$10,000 $30,000 ** depending on condition).
- **Consider a "restomod" approach** (modern interior, suspension, and electronics while keeping the classic body).
2. **If you want a ready-to-drive classic:**- **Prioritize a 1967 model** (better reliability, emissions compliance, and parts availability).
- **Avoid high-mileage examples** unless they have **complete service histories**.
- **Test the engine thoroughly** (listen for knocking, check compression, inspect for leaks).
- **Consider a "driver s car" version** (e.g., **Mach 1, Boss 302, or Shelby GT350**) for better handling and performance.
3. **If you're on a budget:**- **Look for a 289 or 302 with potential** (cheaper to buy but may require more work).
- **Join Mustang forums** to find **hidden gems** (e.g., **eBay, Craigslist, or local clubs**).
- **Start with a simpler project** (e.g., **engine swap, suspension upgrade, or paint**) before tackling full restorations.
4. **Final Verdict:**- **Best for:** Enthusiasts who love **building, racing, and driving a true muscle car**.
- **Not ideal for:** Those seeking **a practical daily driver or a low-maintenance vehicle**.
