Torque Converter High-stall or Low-stall which is better for 240 200

Stall refers to the non-linear coupling between the input and output or stator and rotor turbines. There is a speed below which very little torque is coupled from input to output. This speed depends on the design of the turbines. High stall allows the engine to rev higher before being loaded or coupled to the drive train. Hence, the engine is higher up it's horse power curve. This is a common practice in drag racing. This gives better acceleration at the expence of milage and wear. A lower stall speed gives a quiter and more economical ride. The stall speed in RPM is probably not very different in street car transmissions and represents fine tuning by the manufacturer for each model. You should be able to get the stall spec for your model and what models used the other speeds from the shop manuals.
