Slant six or v8 swap for use in a truck

Appreciate all the input, a turbo would be pretty cool not going to lie, and I honestly don't have the money to do a swap. Unless I find an old dodge with everything in it and tweak the engine abit. Wouldn't mind building the slant up. Save and cash, order the gaskets and finding a place to mill the head. Oversized valves? How do I go about acquiring these? Like what am I looking for. And as far as a cam goes, what cam would you guys recommend?
