SB or BB a body debate

I'm leaning toward a 408 small block for the simple reason I won't have to make headers (yes they're the same cost ($5xx or so BUT I won't have to make them - 383 or 440 based I'd have to make them in order to get what I want out of them)

I'd have to go though SharaDon's to find a 400 block and that means more $$$ and then what would I do with this 360? I had it on CL for 2 months at best offer and haven't gotten 1 email...
