Years ago, Iowa had a "Super Heavyweight" class that had no top limit. They had a kid one year that weighed over 400 pounds. From what I was told you had to weigh at least 240 or 250 to wrestle it. Apparently it died off because some schools didn't have anyone big enough as well as it promoted being fat. Again, that's just second hand.
You just kinda wasted my precious time But don't think twice, it's all right Bob Dylan, 1963
