Nitrous Holeshot 2400 for Ford 1970 to 1982 Application: Ford 1970 to 1982 step case C4 with 10.5 in. bolt circle, 26 spline input shaft, 1.375 in. crank pilot. HoleShots are furnace brazed and include more sophisticated bearings. Consequently they are able to withstand much more torque and horsepower. Nitrous engines produce some serious horsepower and require a serious torque converter to handle it. The newest line of street performance converters from B&M is the Nitrous Holeshot series. Built with the same features as the other B&M Holeshots with the addition of anti-balloon plates. The anti-balloon plates will allow these converters to stand up to the instant horsepower nitrous delivers. Converters with higher than stock stall speed will allow the vehicle to accelerate better from a dead stop and it will allow the vehicle to idle better when a big cam is used. The Holeshot is a good choice for the typical street machine, however when nitrous is used the Nitrous Holeshot is your only real choice. The Nitrous Holeshot 2400 is also an excellent choice for big cubic inch crate motor applications. Fully furnace brazed, heavy duty needle bearing thrust packages and new turbine hubs are the key features along with anti-balloon plates are found in the Nitrous Holeshot converters. These are serious converters for the serious street performance car. Features: Furnace brazed impeller New precision steel alloy pump drive tube New heavy duty needle bearing between stator and impeller (not a thrust washer) Needle bearing between stator and turbine Furnace brazed turbine Dual pattern drive lugs on some GM Holeshots New turbine hub New springs and rollers in stator Anti-balloon plate
