Similar in performance characteristics to the Holeshot series, the Tork Master is B&M's lowest cost performance torque converter.  The Tork Master is an excellent all-around performance street converter.

Stall speed listings are based on an engine producing 230 lb. ft. of torque @2500 rpm.  Similar to average small block.  Engines smaller than 350 cid may not achieve stall speed indicated.  NOT to be used in transbrake applications.
