Converter 350/400 3200-3500 Stall

The ALLSTAR PERFORMANCE Converter 350/400 3200-3500 Stall is a high-performance torque converter engineered for TH350 and TH400 automatic transmissions. Built to manage engine power transfer efficiently, this converter delivers a 3200–3500 RPM stall speed, making it ideal for street performance, bracket racing, and driving scenarios where responsive throttle engagement and smooth power delivery matter. The 10.750-inch bolt circle ensures direct OEM compatibility without modification, reducing installation complexity and ensuring proper fit.

The 3200–3500 RPM stall specification positions this converter in the moderate performance range—higher than stock applications but conservative enough for reliable daily driving and consistent drag-strip repeatability. At this stall speed, the converter locks efficiently after initial acceleration, minimizing heat buildup and improving fuel economy during cruising while still providing the launch characteristics needed for traction-limited launches. Weighing 24.06 lbs, the unit integrates seamlessly into existing TH350 and TH400 drivetrain packages without requiring supplementary balance work on most applications.

This converter suits drivers pursuing moderate power increases, those upgrading from stock torque converters to improve throttle response, and enthusiasts building bracket-racing platforms where repeatability and predictable stall characteristics are essential. The combination of stall speed and compatibility with both TH350 and TH400 transmissions makes it a versatile choice for Chevrolet small-block and big-block applications across multiple decades of domestic muscle cars and performance builds.

ALLSTAR PERFORMANCE has built a reputation for producing transmission components that balance street manners with proven race-track performance. The 3200–3500 stall range reflects engineering optimized for drivers who need better launch feel without sacrificing highway usability—a practical middle ground for both weekend warriors and serious competitors.
