5.0 in a 2005 ford ranger?
I wouldn't swap the engine in a three year old car, man. If you are hell-bent on doing it, i wouldn't use any ten year old components doing it. Go with the crate motor, that way not only will you get a brand new fresh, powerful motor, but you won't be scrapping a bunch of older parts together. If this was like a 85 or a 95 ranger, then hell yeah i'd say build up that 302 from a wrecked Stang or Explorer or Mark VII, whatever, but nah, your truck is still a baby.
