Review SCAT Flexplate fits STREET

The **Scat FP-350L Street Flexplate** is a high-performance, bolt-on clutch and flywheel assembly designed specifically for Ford s 5.0L (351C) and 5.8L (355C) Cobra Jet and Police Interceptor engines, as well as select 7.0L (428) applications, making it an ideal choice for enthusiasts seeking a seamless transition from stock to high-performance drivetrains. Engineered with precision, this flexplate combines a forged steel hub with a high-quality, multi-disc clutch pack that delivers exceptional engagement and disengagement characteristics, ensuring smooth power delivery while minimizing wear on the transmission. The FP-350L features a **350 lb-ft torque capacity**, accommodating the increased demands of modified engines without sacrificing reliability, and its **dual-mass design** helps dampen torsional vibrations, reducing transmission strain and improving overall drivability. The flexplate s **heavy-duty splines** and **precision-machined hub** ensure a secure, vibration-free connection to the crankshaft, while the **high-friction clutch facings** provide consistent engagement under heavy loads, whether cruising on the highway or launching from a stoplight. Built to withstand the rigors of daily driving and spirited performance use, the FP-350L is compatible with a wide range of Ford transmissions, including the **C6, 4R70W, and 4R75W**, making it a versatile upgrade for both street and light track applications. Whether you re running a stock engine with a mild tune or a heavily modified powerplant, the Scat FP-350L Street Flexplate delivers the durability, responsiveness, and smoothness needed to maximize your vehicle s potential without the complexity of a full drivetrain rebuild.

**Pros and Cons of buying a Scat FP-350L Street Flexplate**

The Scat FP-350L Street Flexplate is a popular choice for performance applications, particularly in muscle cars and trucks with Ford 7.5-inch rear axles. Below is a detailed breakdown of its advantages and disadvantages.

### **Pros**

1. **High Torque Capacity** The FP-350L is designed to handle up to 350 lb-ft of torque, making it suitable for heavy-duty applications, including high-performance engines and towing setups. This is significantly higher than stock flexplates, which are often rated for much lower torque levels.

2. **Durability and Strength** Constructed from high-quality steel, this flexplate is built to withstand extreme stress without warping or cracking. The reinforced design helps prevent common issues like flexplate breakage or distortion under heavy loads.

3. **Compatibility with Performance Applications** It is engineered to work well with high-performance engines, including those with forced induction (turbocharged or supercharged) or large displacement (big-block) setups. This makes it a solid choice for drag racing, street cruising, and towing.

4. **Reduced Vibration and Smooth Operation** The FP-350L features a balanced design that minimizes vibration, leading to a smoother drivetrain experience compared to weaker or poorly balanced flexplates.

5. **Easy Installation** Like most flexplates, it is designed for straightforward installation, though some modifications (such as flywheel alignment or bolt pattern adjustments) may be required depending on the vehicle s setup.

6. **Cost-Effective for Performance Use** While more expensive than stock flexplates, it offers a balance between cost and performance, making it a practical upgrade for enthusiasts who want reliability without excessive expense.

7. **Warranty and Support** Scat offers warranties on their products, providing peace of mind for customers who invest in performance parts. Their customer service and technical support are often praised for assisting with installation and troubleshooting.

### **Cons**

1. **Higher Upfront Cost** Compared to stock or aftermarket flexplates with lower torque ratings, the FP-350L is more expensive. This can be a significant investment, especially for budget-conscious buyers.

2. **Potential Overkill for Mild Applications** If the vehicle is used primarily for light-duty driving (e.g., daily commuting with a stock engine), the FP-350L may offer more capacity than necessary. In such cases, a lower-rated flexplate could suffice, saving money without sacrificing performance.

3. **Requires Proper Installation** Like all performance parts, the FP-350L must be installed correctly to avoid issues such as misalignment, improper bolt torque, or damage to the transmission or engine. Improper installation can void warranties and lead to premature failure.

4. **Limited Customization** The FP-350L is a standard flexplate and does not offer customization options (e.g., weight reduction, unique bolt patterns, or specialized balancing). Buyers who need non-standard specifications may need to look elsewhere.

5. **Weight Considerations** While the increased strength comes with added weight, this may not be a major issue for most applications. However, in high-performance racing (e.g., drag racing), a lighter flexplate could theoretically improve acceleration.

6. **Compatibility Issues with Some Engines** Depending on the vehicle s specific drivetrain setup (e.g., automatic transmissions with unique bellhousing designs), there may be compatibility concerns. Always verify fitment before purchasing.

7. **Potential for Over-Torquing** If the engine or drivetrain is not properly matched to the flexplate s capacity (e.g., a heavily modified engine with inadequate supporting components), the FP-350L may still fail if the system is not balanced. This underscores the importance of a holistic performance upgrade.

### **Conclusion**

The Scat FP-350L Street Flexplate is an excellent choice for enthusiasts looking to upgrade their drivetrain for higher torque applications, whether for towing, performance driving, or racing. Its strength, durability, and compatibility with a wide range of engines make it a reliable and popular option. However, it is not without drawbacks primarily its cost and the need for careful installation and system matching.

For most muscle cars, trucks, or performance applications where torque exceeds the limits of stock components, the FP-350L is a worthwhile investment. It strikes a balance between performance and practicality, offering significant benefits over weaker flexplates without being overly complex or expensive for its class.

### **Recommendation**

- You are running a high-torque engine (e.g., big-block Ford, turbocharged setup, or towing application).

- You want a durable, vibration-reducing flexplate that will last under heavy loads.

- You are willing to invest in a performance part that will support your drivetrain s demands.

- Your application involves very mild use (e.g., stock engine in a daily driver with minimal torque).

- You are on a tight budget and can find a sufficiently rated flexplate at a lower cost.

- You lack experience with performance drivetrain upgrades and cannot ensure proper installation.

For most serious enthusiasts, the FP-350L is a strong recommendation provided it is paired with the rest of the drivetrain components (transmission, differential, etc.) that can handle its torque capacity. Always consult with a mechanic or performance specialist to ensure full compatibility with your vehicle s setup.
