rear suspension ????

[t4keumbw]

65 c10 rear suspension. I am in the process of building a 1956 c10. I am installing air ride suspension on the truck and I was looking for someone to answer a question for me.
I am using a 2001 5.3 engine with a few goodies should be around 400 horses when done. Should I use a four link setup or a triangulated four link? Not going to be drag raced much and might do a little twisty turny road coursing. But still unsure about what rear suspension. Any help will be greatly appreciated.
