B&M 20483 Holeshot 3200 Stall Torque Converter

The B&M 20483 Holeshot 3200 Stall Torque Converter is engineered for GM automatic transmissions and vehicles with performance engine modifications, particularly those equipped with aggressive camshafts that reduce low-end power output. This high-stall converter is specifically designed for 1965-1991 GM TH400, TH425, and TH375 transmissions, as well as 1968-1981 TH350 and TH375B transmissions (not compatible with 350C models).

Key Features:

• 3200 RPM stall speed launches vehicle in higher RPM range where peak torque is available
• Furnace-brazed impeller and turbine construction for maximum durability
• Precision steel alloy pump drive tube ensures reliable power transfer
• Heavy-duty needle bearings between stator and impeller (replaces standard thrust washers)
• Needle bearings between stator and turbine for reduced friction and improved efficiency
• Optimized for big cam engines and modified powerplants

The higher stall speed allows modified engines to launch in their optimal power band, resulting in dramatically improved acceleration and reduced elapsed times. This converter is an excellent choice for street/strip vehicles, muscle car restorations, and any GM-powered vehicle with significant engine modifications where stock converter stall speed is inadequate for optimal performance.
