### **Pros of the Cardone 67-6039 Throttle Body**
1. **High-Quality Materials and Craftsmanship**
The Cardone throttle body is known for its durable construction, often featuring stainless steel components and precise machining. This reduces the risk of leaks, warping, or premature failure compared to OEM parts, which can degrade over time.
2. **Improved Performance and Throttle Response**
Many users report smoother throttle response and better acceleration, especially when paired with a performance carburetor or fuel injection system. The Cardone unit is designed to minimize vacuum leaks and provide a cleaner fuel-air mixture, which can enhance engine efficiency and power.
3. **Compatibility with Aftermarket Modifications**
This throttle body is widely compatible with a variety of performance upgrades, including:- **Performance carburetors** (e.g., Holley, Edelbrock, or Weber)
- **Fuel injection systems** (e.g., Holley EFI, Moroso, or standalone ECU setups)
- **High-flow air intakes** and exhaust systems
The Cardone part is often preferred over OEM units because it can handle higher airflow rates without choking.
4. **Reduced Vacuum Leaks**
OEM throttle bodies on older GM engines are notorious for developing leaks around the throttle plate or gaskets, leading to rough idling, stalling, or poor fuel economy. The Cardone unit is engineered to seal better, reducing these issues.
5. **Easy Installation**
The part is designed to drop-in replace the stock throttle body with minimal modifications required. It includes gaskets and mounting hardware, making the installation process straightforward for most mechanics or DIY enthusiasts.
6. **Positive Feedback from the Community**
The Cardone 67-6039 has a strong reputation in the classic car and performance tuning communities. Many owners of restored or modified GM small-blocks swear by it for its reliability and performance benefits.
7. **Cost-Effective Upgrade**
While not the cheapest option, it is often more affordable than a full carburetor or fuel injection overhaul. For those looking to improve their engine s drivability without a complete rebuild, this is a pragmatic choice.

### **Cons of the Cardone 67-6039 Throttle Body**
1. **Potential Fitment Issues**
While the Cardone unit is designed for GM small-blocks from the late 1960s, slight variations in bolt patterns or mounting holes can occur depending on the specific engine or year. Some users may need to file or modify the mounting surface slightly for a perfect fit. Always verify compatibility with your engine s build year and modifications.
2. **Requires Proper Tuning**
If you are running a carburetor or fuel injection system, the throttle body alone may not be sufficient to optimize performance. You may need to adjust the carburetor jets, fuel pressure, or ECU maps to match the throttle body s airflow characteristics. Improper tuning can lead to lean mixtures, rough idle, or even engine damage.
3. **Not a Standalone Performance Solution**
The Cardone throttle body improves throttle response and reduces leaks, but it does not significantly increase horsepower on its own. For meaningful power gains, it should be paired with other modifications such as a high-performance carburetor, fuel pump, or ECU upgrade.
4. **Potential for Aftermarket Parts Compatibility Issues**
If you are using non-OEM components (e.g., a different carburetor brand or a custom intake), there might be clearance issues or mismatches in mounting points. Always check compatibility with your specific setup before purchasing.
5. **Limited Availability of Replacement Parts**
While Cardone is a reputable brand, some users have reported difficulty finding replacement gaskets or seals for the throttle body if they wear out. Stocking up on spare parts is advisable if you plan to keep the engine running long-term.
6. **May Not Be Ideal for Extreme Builds**
For highly modified engines (e.g., big-block conversions, forced induction, or extreme nitrous setups), the Cardone throttle body may not be sufficient. In such cases, a more aggressive aftermarket unit (e.g., from Holley or Edelbrock) might be necessary.
7. **Installation Knowledge Required**
While the installation is generally straightforward, improper sealing or gasket placement can lead to leaks. Those without mechanical experience may need to consult a professional to ensure a proper fit.

### **Conclusion**
The **Cardone 67-6039 Fuel Injection Throttle Body** is an excellent choice for owners of classic GM small-block engines looking to improve throttle response, reduce vacuum leaks, and enhance drivability. Its high-quality construction, compatibility with aftermarket systems, and ease of installation make it a popular upgrade. However, it is not a magic bullet for performance it works best when paired with complementary modifications like a performance carburetor or tuned fuel system.
For most **1967 1972 GM small-block owners** running stock or mildly modified engines, this throttle body is a worthwhile investment. If you are planning significant power upgrades (e.g., forced induction or extreme carburetion), you may need to explore more aggressive aftermarket options.
