* Increased Engine Load: A higher stall speed means the engine needs to work harder to overcome the converter's resistance. A stock engine isn't designed for this sustained high RPM under load, potentially leading to overheating, excessive wear, and even damage.
* Poor Drivability: A 3500 stall converter will make the car very difficult to drive smoothly around town. You'll experience excessive engine lugging at low speeds and a jerky, unpredictable feel.
* Transmission Strain: While the converter itself is designed for high torque, the added strain placed on the transmission might exceed its tolerances, leading to premature wear or failure, especially if it's a stock transmission.
* Fuel Economy Impact: The constant high RPMs needed to overcome the stall will significantly reduce your fuel economy.
While it *might* technically work for short periods, consistently running a 3500 stall converter on a stock engine is not recommended. It's better suited for modified engines with increased horsepower and torque to handle the extra load. A lower stall converter, more appropriate for your engine's capabilities, is necessary for a smoother, more reliable, and efficient driving experience.
