Radiators: Is 22" enough for 400 HP?

long story short I started with the slightest of upgrades (several fans, water pumps,thermostats,shrouds, radiators) and now I ended up with a 27" radiator and a Ford Taurus 2 speed fan. You never know when your going to be stuck in traffic or car cruise watching the temp gauge creep up. You start calling friends asking if 230 is ok. Second guessing your 160 stat. Your kids are in the back "why is the car smoking daddy"
