B & M flexplate

Ok just for the heck of it i held up my new B&M converter to the factory flex plate thats still attached to the 2001 5.9 Magnum. it fits and the holes seem to align up. Since this is a weighted flex plate and the converter is a neutral balance, should it just hook it up and see if it runs?No one I called claimed they had ever heard of using this type of applications before (2001 5.9 Magnum to a A727TF with a non-lockup B&M 2400 stall speed converter). Any ideas?

Do your homework,and get it right before you hook it up.
