Manufacturer: B&M
Part Number: 20485

Fitment
10-inch diameter, 10.75-inch bolt circle, 3500-3800 RPM stall

Description
"B&M Nitrous HoleShot 3800 stall for GM 1965-91 TH400, TH425, TH375 and 1968-81 TH350, TH375B (not TH350C.) The Nitrous Holeshot 3800 stall converter is an excellent choice for vehicles with engine modifications, particularly big cams that tend to reduce low end power and torque. 
The higher stall speed of this converter will launch the car in a higher rpm range where more torque is readily available, resulting in quicker acceleration. Nitrous Holeshot converters feature furnace brazed impeller and turbine, new precision steel alloy pump drive tube, new heavy duty needle bearings between the stator and impeller (not a thrust washer) and needle bearings between the stator and turbine. 
Other features include a new turbine hub, new springs and rollers in the stator and anti-balloon plates. The anti-balloon plates will allow these converters to stand up to the instant horsepower that a Nitrous plate or fogger system delivers.  These are serious converters for serious performance street cars. To prevent contamination left from worn parts being circulated in your new components causing premature wear, we strongly recommend protecting your investment by adding a B&M transmission cooler with all new transmission installations. Listed converters are NOT to be used in trans-brake applications. Not for use in trans-brake applications."

Installation Notes
"Fits vehicles with GM TH400, TH425, TH375 & TH350, TH375B (Not TH350C) Automatic Transmissions NOTE:
"NOTE:
- Stall speed listings are based on engines producing 230lb. ft. of torque at 2,500 rpm. More torque at 2,500 rpm will give you a higher stall speed, less torque at 2,500 rpm will give you a lower stall speed than the stall speed ratings than indicated in the description."
