Radiators: Is 22" enough for 400 HP?

22" 3 core champion with spal 2052 dual 11" pullers. With minimal trimming the Spal fits like it was made for it. Drivers side fan runs off the controller at the top front of driver side inner fender, and the sending unit in the intake. The second is switched from a toggle on the dash. Normal driving is fine, the magnum is happiest around 190-195, but there's plenty traffic here and its hot so i have to flip the toggle on for the second fan when it gets above 210, then it returns to 185-190 real fast. I don't usually leave the pass. side fan on needlessly since it draws a lot of power. The amp is a 140 amp. powermaster and the car has been rewired because I'm using electric everything, even seats.
You can also see the water pump pulley would run interference with a single fan set up, even with duals the clearance is minimal. The Spal had the thinnest gap between the fans that I could find, plus the fit was a pleasant surprise.
360/380 crate magnum, 904, 3.91 gears
