Compatible with 1966-1991 Ford C-6. 11 in. diameter, 11.4 in. bolt circle, 3500-3800 RPM stall; B&M NOS Holeshot 3800 stall for 1966-91 Ford C6 transmissions with a 1.375 in. crank pilot, 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. NOS 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.
