727 Torque Converter

The converter is neutral balanced so I am going to go the budget friendly route with the correct weighted balancer and B&M flex plate.
I'm glad to see that you chosen the route you're going. You never mentioned if the converter you've got is yours or something you've picked up. I see the photo of a transmission with the converter attached has been removed, but I'd like to point out that the weight that is welded on to the front cover is not a factory weight nor have I ever seen one like that from any of the converter builders I've dealt with over the years. Just my observation.
