Got me a new truck with a slant Six, what should I do?

I got it for less than what the guy was asking. I saw it on craigslist and thought I had to have this truck haha. I love tinkering on things so I just can't leave it be.

I'm thinking a comp cam 264S

A 390 four barrel carb and an offenhauser intake and some headers. If anyone has any of these parts for sale, I might be interested. I have nothing but time to dream up what I want to do with this truck haha, oh and now that I have this one, my 87 RAM short bed is up for sale. The pic is a little old and right now its sitting in a storage unit in Manhattan, Kansas.
