- HoleShot 2400 for GM 1965 to 1991 TH400, 425, 375 and 1968 to 1981 TH350, 375B (not 350C) are for serious-minded performance enthusiasts and offer additional strength and durability features not found in our Tork Master or Traveler series of converters. The Holeshot converter is an excellent choice for vehicles with some performance 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. Holeshot converters feature furnace brazed impeller fins and turbine, new precision alloy impeller hub and new heavy duty needle bearings. Other features include fully balanced and pressure tested by expert technicians. If your vehicle is equipped with a plate type nitrous system or supercharger, please refer to the Nitrous Holeshot line of converters. Notes: 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 more stall speed, less torque at 2,500 rpm will give you less stall speed than the stall speed ratings indicated. Higher stall converters can generate more heat, so we highly recommend adding a transmission cooler. This converter is Not recommended for supercharged, plate-type nitrous oxide or trans-brake applications.

In the 50s it was B&M who came up with the idea of using a performance reinforced Hydramatic for racing. In the 60s it was B and M who developed shifters to go along with it, and later in the decade came race converters. In the 70s shift and transmission improving kits, and always the constant refinements and expansion of existing product lines.
If you've ever raced a vehicle, or driven a hot rod with an automatic transmission, high stall torque converter, an aftermarket automatic shifter, or performance enhancing shifting kit - thank B&M. From Trick Shift performance ATF to reverse pattern valve bodies, 1.80 gear sets to cool canisters, the list of firsts goes on and on.
