B & M – B & M Torque Converter, Holeshot 2500, 50451 (Part No.50451)

B & M Torque Converter, Holeshot 2500, 50451

from

$727.99
This Holeshot 2500 fits 1970-82 Ford C4 automatic transmissions with 26 spline input, 1.375 crank pilot and a 10.5-inch bolt circle. Holeshot torque converters are for serious-minded performance enthusiasts and offer additional strength and durability features not found in our Traveler or Tork Master series of converters. The Holeshot 2500 converter is good 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.
