The Climber(1975)

Original title: L'ambizioso

Joe Dallesandro plays a hungry young buck who aspires to be a career criminal. He starts out working at a warehouse for a gangster where he helps to relocate illegal contraband, and because of his ruthlessness and dependability he begins to ascend the ladder of organized crime. Of course, the more powerful he becomes, the more "Climbers" come out of the shadows to take his place.
