What budget torque converter?

What was the stock stall rated at in the 340's? I'd like to know what I have since I bought the car with what was described as the stock stall converter.
Around 2200/2500 is what I remember getting in the Duster. A real 340 converter has been hard to find for a number of years. At the converter company I worked for in the past, 340 converters were core in first.
