The other day my mind was wandering as I was shopping for a new converter and I came across a question in my mind that I feel needs a solid answer. To the best of my knowledge, the purpose of the stall is to allow the engine to rev more freely until it is in it's optimal power range for the purpose of the motor.
In the case of a stout 440 where it will make a significant amount of torque say 500lb ft from the 2500 rpm range and up, what is the benefit of having a 3500 plus stall in the same motor? If a big cammed 440 is making over 500lb ft of power around 2500 rpm but increases it's torque through say 5000 rpm and max rpm is 6500. Said engine with a stall speed that is at 3800 rpm per the cam grinder recommendation. In this scenario, are you not wasting the torque the engine is producing below that 3800 rpm point? I guess in short, why use a high stall converter if your engine produces usable power at a lower RPM range?
