Welcome to My (And Not Sly's) House
As far as all time, the McGuire Twins, a freak show team from the 70s that weighed over 700lbs each. As for modern wrestling, Big Show and Kane probably. Big Show and Khali teamed once or twice but it was never a regular thing. There's a team from Puerto Rico called the Headhunters who were both huge. For a regular team though, unless I'm overlooking someone and I probably am, it's Kane and Big Show.
As for a team like that, probably Andre's team from the 87 Survivor Series, with Andre at 520, OMG at 400 and Bundy at 400 with Rude and Reed combining for another 500.
