There is no possible way that Johannsen could hang with Lewis. Lewis's vastly superior size, power, and skill repertoire make this an easy knockout. It wouldn't go more than five rounds, and if it lasted that round, it's because Lewis is taking his time. Johannsen was a respectable fighter in his prime. But he would be no more than a cruiserweight today.
Ingemar Johansen KO1. he lures him and wears him out by holding, running and clinching, before putting him to sleep at the 15 minute mark. if for no reason other than me wanting to level the playing field of all those who have given no consideeration to the LPR rules.
