What was the stall speed on that converter? I'd go with a new 2500 JMBX for my 6L80, but I want a slightly higher speed to better match the cam I'm installing.

Whatever STOCK is I guess

Contact your cam manufacturer and they will recommend a stall speed range based on the cam grind, vehicle weight, intended usage pattern and final drive ratio. That is the best way to determine the appropriate stall. You want your converter to be "matched" to your cam and where it makes a preponderance of it's power.
