Used 360 price

I have a friend into Mopars and he mentioned that I have to change the torque converter as well going to the 360.

I have access to the 360 car oil pan and pick up tube.Machine shop I have my engine machine work done at said they are mine picking them up tomorrow.Called the owner tonight I know very well,gave them to me
If I remember correctly you can save money by keeping the same torque convertor and using a flex plate with the balancing weights on it.
