I have a database of 549,846 HD games from the last couple of years.
The highest score I have in that database is 144 points by D3 Greensboro in season 70 in Rupp.
The highest combined total I have in that database is 279, in a 142-137 game (D1 Buffalo over D1 Ohio) in season 73 in Knight.
My database only represents about 1/3 of all the games played in that span, though, so there may have been crazier games than those ones. And before you ask for more info, I only scored points totals, so I can't give you any other interesting extreme stats.
