Product Details

The B&M Holeshot 20483 is a high-performance 3200 RPM stall speed torque converter engineered for GM TH350 (1968-1981) and TH400 (1965-1991) automatic transmissions. Designed for street/strip applications, this converter delivers aggressive launch characteristics ideal for modified engines with camshafts and increased compression ratios.

Key Features:

  • 3200 RPM stall speed for improved launch performance and reduced elapsed times
  • Precision alloy steel impeller hub for enhanced strength and durability
  • Copper furnace brazed impeller and turbine construction ensures leak-free operation
  • Precision balanced on certified equipment to eliminate vibration
  • Pressure tested by expert technicians to guarantee quality control
  • Race-proven technology suitable for high-performance street and strip use

The Holeshot series torque converters are specifically designed for vehicles with performance modifications including aftermarket camshafts, increased compression, headers, and intake upgrades. The higher stall speed allows modified engines to launch in their optimal power band, resulting in quicker acceleration and improved quarter-mile performance. Each converter is manufactured to B&M's exacting standards with quality materials and rigorous testing procedures.
