I agree with all thats been said. If you aren't shooting for a great ET at the track, what is left is street manners, feel, and STREET TRACTION. By that i mean why put up with any less responsive converter when a real tight one will still fry the hides? Personally i would shoot for about 2600 to 2800 stall behind your motor. A converter that tight will move out smartly at the tip of the throttle like a stock 440 converter combo (only harder!) and be a blast to drive on the street. A good converter builder should know how tight you can go with the cam specs and other motor specs so it won't fall on its face from a dead stop.
