Factory High Stall Converters

There is no such thing as a factory high stall converter.
So the 2400 340 stall is NOT higher than the 1800 stall 318 2 barrel??? They put that 'higher' stall converter in the 340 for a reason. 2400 is 'higher' than 1800, So that makes it a 'High' stall converter by comparison.
