Description

30-Spline Input Shaft - 10.75-inch Bolt Circle - 3200-3500 RPM Stall

Part Number: 70444

This HoleShot 3500 fits 1984-93 GM TH700R4/4L60 automatic transmissions with a 30-spline input shaft. This converter retains the lock-up feature. Holeshot torque converters 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 3500 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, a 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. The product images shown are for illustration purposes only and may not be an exact representation of the product. 10.75-inch bolt circle.
