Hmmm, we'll if I was spending your money maybe a Thompson 427SC engine like in Steilow's Mayhem and a full Carbon Fiber front clip from Anvil would fit the bill.
Edit, I don't see it in your thread. But if you haven't picked suspension I wouldn't hesitate to do a DSE subframe and Quadralink rear and make sure you put mini-tubs in that thing at the panel replacement stage. You will thank me later on.
