Radiators: Is 22" enough for 400 HP?

Sounds like so much market-ese to me LOL. A 3 row, 22" wide has about 25% more tube area than the same height 2 row, 26" wide. The 3 row's disadvantage is that the 3rd row is not as effective as the the 1st 2 rows at low speeds and idle, since the air temp is higher by the time it reaches the 3rd row.
