You kiddin’? People love to breed those as big as possible and call them ‘bully pits.’ They have breeder pages where they describe the breeding of blue nose pits etc. and brag about the biggest dogs - purebred pits. The AKC won’t register pits that big (or over 40lbs) but the people who breed monster pits are interested in AKC registration.
I had my choice of links on the web -lots of competition among breeders to breed the biggest most monsterous pit bull possible. This page features a 170lb pit bull.

They are no more pit bull than a bull terrier is
They have zero wind and stamina.....they are bred for looks
Average fighting capable pit bull is 40-70 pounds....rangey and sinuous with good lungs
Last pic is a fat lovable slobber bucket bully.....can't fight crap...too fat and squat outta breath but heavy......second is a very nice red nose pit bull like the ones my son in law raises in cheatham county tn which yes is dangerous if not properly owned and supervised.....first is Bedford my Standard American Bulldog from Konfederate kennels in South Georgia...100 pounds..toughest dog I ever owned.....pit bull destroyer and that's saying something..worst enemy a Russian boar has or a black bear....Bedford is at stud in Bordeaux....that's France
