426 Wedge possible install challenges

Hey all

My first post/request for info. I have access to a purpose built, well running 500HP 426 Wedge that a guy is removing from his 69 charger. I have seen it run and it comes with the also purpose built 727 attached. I am wondering what types of challenges I might encounter getting it installed if I was to purchase. It will go into my currently in mid-restoration 67 Dart GT conv automatic that I recently removed a crusty old 273 from. Just wondering if I am attempting something not worth the effort, or is it easier than I am imagining? Just looking for advice on what I need to do in order to accommodate that package into the space in the engine bay. What parts are recommended to make the swap easier?

If there are already threads on this discussion I apologize for starting something already covered....but I look forward to your thoughts and feedback....much appreciated!

Thx
Brad
