The B&M Nitrous Holeshot 2400 Torque Converter, Part #20480 is for 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 Nitrous 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.
Recommended for Street Rod, Pro Street, and Street Machines with Plate Type Nitrous Systems Nitrous engines produce some serious horsepower and require a serious torque converter to handle it. Built with the same features as the other B&M Holeshots with the addition of anti-balloon plates. The anti-balloon plates will allow these converters to stand up to the instant horsepower nitrous delivers. Converters with higher than stock stall speed will allow the vehicle to accelerate better from a dead stop and it will allow the vehicle to idle better when a big cam is used. When nitrous is used the Nitrous Holeshot is your only real choice.
