Big Block Advice?

Well, I would build a small block for it if I already had a 318, 340, or 360. But I have a slant in it right now. As for the rear, it's stock (I believe that's an 8 1/4?). I should have the disc brakes within the next week or two. Thanks sgbarracuda. I might take you up on that offer if I can't find anything a little closer. Thanks everybody for all of your advice, I really appreciate it.
