### Pros and Cons of Buying a NOS (New Old Stock) Ford C9ZZ-6565-A Push Rods Set for a 1969-1970 Boss 302 Mustang
#### **Pros:**1. **Authentic and High-Quality Components** NOS parts are original, factory-new items that were never installed or used, ensuring they meet the exact specifications of the original design. This reduces the risk of wear or damage from prior use.
2. **Reliability and Durability** Since these push rods were manufactured to Ford s original standards, they are built to last under proper maintenance and use. They are less likely to fail prematurely compared to aftermarket or rebuilt parts.
3. **Preservation of Originality** If you are restoring or maintaining a classic Mustang to stock specifications, NOS parts help preserve the vehicle s authenticity, which is highly valued in the collector s market.
4. **Compatibility** The C9ZZ-6565-A push rods are designed specifically for the Boss 302 engine (used in 1969-1970 Boss 302 Mustangs), ensuring a perfect fit without the need for modifications.
5. **Potential for Increased Value** Using NOS parts in a restored or well-maintained Boss 302 can enhance the car s resale or collector value, as enthusiasts often seek original components.
6. **Reduced Risk of Failure** Unlike aftermarket parts that may have inconsistent quality, NOS parts are guaranteed to function as intended by Ford, reducing the likelihood of engine issues related to push rod failure.
7. **Historical Significance** Owning NOS parts allows you to own a piece of automotive history, as these components were part of the original production run of one of Ford s most iconic engines.

#### **Cons:**1. **High Cost** NOS parts are significantly more expensive than aftermarket or rebuilt alternatives. The price reflects their rarity, authenticity, and the fact that they were never used. This can be a major financial investment, especially for a single component like push rods.
2. **Limited Availability** NOS inventory is finite, and popular parts like these may sell out quickly. Once they are gone, they are gone forever, which can create urgency and drive up prices further.
3. **Long Lead Times** Even if the part is available, sourcing NOS components can take weeks or months, depending on the seller s inventory and demand. This can delay restoration or maintenance projects.
4. **Storage and Handling Risks** NOS parts are often stored in environments that may expose them to dust, moisture, or temperature fluctuations over decades. While they are typically sealed in their original packaging, there is still a slight risk of minor wear or contamination if not handled carefully.
5. **Overkill for Some Applications** If you are not planning to compete in high-performance or restoration circles, NOS push rods may be unnecessary. Aftermarket push rods that meet or exceed OEM standards could suffice for daily driving or light modifications at a fraction of the cost.
6. **Potential for Overpaying** The NOS market can be speculative, with some sellers inflating prices due to demand or perceived rarity. Buyers must research fair market value to avoid paying more than necessary.
7. **Maintenance and Care Requirements** NOS parts require careful handling and storage to maintain their condition. If not properly cared for, they may degrade over time, negating some of their advantages.

### **Conclusion:**The decision to purchase a NOS Ford C9ZZ-6565-A push rods set for your 1969-1970 Boss 302 Mustang ultimately depends on your priorities, budget, and goals for the vehicle. If authenticity, reliability, and long-term value are your top concerns, and you are willing to invest the higher cost, NOS parts are an excellent choice. They offer peace of mind and contribute to the preservation of your Mustang s originality.
However, if budget is a constraint or if you are not aiming for a fully restored or high-value project, aftermarket push rods that meet or exceed OEM specifications may be a more practical alternative. These can provide similar performance at a lower cost without the same level of exclusivity.
