1. For most standard applications:
- 10-inch torque converter: Suitable for lightweight vehicles (under 3,000 lbs) with a 350 engine and automatic transmission. Provides good balance between fuel economy and performance.
2. For performance applications:
- 11-inch torque converter: Often preferred for drag racing or other high-performance situations. It offers better low-end torque and acceleration but may slightly reduce fuel efficiency.
3. For towing and heavy-duty applications:
- 12-inch or larger torque converter: Recommended for vehicles used for towing or carrying heavy loads. Provides increased pulling power but may affect fuel economy and overall performance.
When choosing a torque converter, it's essential to consider the entire drivetrain package, including the transmission, rear axle ratio, and vehicle usage. If unsure about the proper size, consulting a reputable transmission shop or performance specialist is advisable. They can help you select the most appropriate torque converter to meet your specific needs and objectives.
