Internal balance 360

[Aussie Challenger]

Can anybody tell me how hard it is to balance a LA 360 internally, I know about having to have different harmonic balancer and flywheel/convertor.
I am using lighter con rods and pistons so was thinking as I will have to have the crank balanced anyway I might look at internally balancing it.
Having to add metal costs I know but it could be minimal using the lighter pistons and rods.
Has anybody had it done?


Thanks in advance.
