One hit that he doesn't get credited/blamed for is Long John Martorano. I think most folks assume Ligambi ordered that done, because Martorano was making noise about trying to take over, but if you read Bobby Simone's "The Last Mouthpiece," there's a snippet where Simone is on trial himself and Crazy Phil Leonetti is testifying against him. Leonetti relates that Simone was worried Martorano was going to kill him and his son (because the son, Cowboy George, got a life sentence after Simone encouraged him to plead guilty), and Scarfo told Simone, "don't worry, the second he gets out of jail, Patty Specs has the contract to kill him."

I think posters here and George Anastasia also have argued that Johnny and Stevie Gongs did that hit, along with Anthony Nicodemo, but maybe the initial contract was still left over from Scarfo days?
