Apply a good coating of chili powder, salt and black pepper to Boston Butt and place on a broiler pan uncovered fattest side up. Add several cups of water to the broiler pan and place in an oven or smoker at 225 degrees for 6 to 8 hours or until internal temperature is at least 160 degrees F. and meat easily pulls from the bone.  If you want to turn the meat every few hours that is ok too.
