5.9 magnum 2002

Hi there.
I have a 5.9 MAGNUM from 2002. I know its external balance. But I wonder, is it not possible to change that so it will be internal balance? or neutral balance? I have a 318 with a 727 that I want to use parts from. like the balancer in the front, and the 727 with the flex and converter in the back.
Please feeback :D

Why change it? The motor, balancer and flex plate are all matched to the 5.9 Magnum. A stock, neutral balanced torque converter will bolt right up and be happy. You should be able to file one of the holes in the flex plate to slightly align the torque converter from the 727. Just make sure it doesn't have weights on ot from a cast crank 360!
