Sound like you are building a real bomb.Sounds good. Just my opinion,but I would use an independent front suspension with power rack and pinion steering. I am running a 350 SB in my 55-2 and I used the blockhugger headers to clear things up. I dont know if they make blockhuggers for big blocks,but you might want to check that option out.Like I said the independant suspension is my choice,I am sure you will get many opinions against it here.
