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?

countless guys have used every day 727's behind 360 magnums. If the original converter from the truck the engine came from was neutrally balanced it'll work fine.
