Torque Converter, Holeshot, 3,400-3,800 rpm Stall Range, Chevy, TH400/TH375/TH350/TH375B, Each

A higher-than-stock stall speed as delivered by these B&M Holeshot converters will provide several advantages and benefits to vehicles with modified engines. Many modifications, particularly big cams, tend to reduce low-end power and torque. These high-stall converters allow the engine to launch the car at higher rpm, where more torque is available. They're a very good choice for the typical street machine that is looking for better launch capability and more strength.
