B&M – High Performance Automatic Transmission Torque Converter
Description
The B&M Holeshot 2400 torque converter (Part# 20412) is designed for GM TH350, TH375, TH375B, TH400 and TH425 automatic transmissions (1965–1991). With a stall speed of 2,300–2,500 RPM, it improves launch capability and delivers more torque in the powerband of a modified engine. Stall speed ratings are based on engines producing 230 lb-ft of torque at 2,500 RPM; more or less torque at 2,500 RPM will yield a higher or lower stall speed accordingly. Requires a 10.75 in. bolt circle or dual pattern flexplate. Due to converter core availability, the actual converter size may vary but performance functionality will be as advertised. (See Application Section)
