Torque converter question

My wood hauling truck has a 1965 383 engine with 727 Tranny in it now but the motor is getting weak. I have a 440 from a motor home that is either a 1975 or 76 that I want to swap out. Will the torque converter from the 383 work with the 440 or are they balanced different? I just had the Tranny rebuilt and bought a new torque converter so I would like to use it if possible. Thanks for the info.
