Question Planning tranny swap....

I will be dropping in a 406 in my truck in the near future. My current tranny is the original powerglide that is tired and simply boring. My problem is I can't decide between a th350 or the th400. The engine puts out upwards of 470hp and 520 ft.lbs so I want something that can handle what i put to it. Does anyone run this kind of power and if you do, what is your setup???
