The B&M Holeshot 3600 Torque Converter, Part #20425 fits 1965 to 1991 General Motors TH375, TH400 & TH425 automatic transmissions and 1968-1981 GM TH350/TH375B transmissions but does not fit GM TH350C models with locking torque converter.
The Holeshot converter will provide several advantages and benefits in vehicles with modified engines. Many modifications, particularly big cams, tend to reduce low end power and torque. The Holeshot converter allows the engine to launch the car at higher rpm where more torque is available.
The Holeshot is a very good choice for the typical street machine that is looking for better launch capability and more strength. Street rods with modified engines will also benefit from a Holeshot converter.
