Sonny Liston, 1962-63 vs Oscar Bonavena, 1966-1970, who wins?

Seeing as Oscar nearly knocked Frazier out in 2 rounds in their first fight and was only ever beat inside the distance by Ali in 60 odd fights how would he (1966-1970 verion) do against Liston or even Foreman, Tyson, Norton, Cooney, Lewis, Louis, Bowe, Tua, Holyfield, Holmes, Shavers, Quarry, Mercer, Haye, Bruno, Morrison, the Klitschkos and anybody else with awesome or reasonable power? And that was a beautiful knockout Ali handed Bonavena ie coming in the closing seconds of the 15th and last round lol.
