Radiators: Is 22" enough for 400 HP?

So, since nobody asked, I will!! What is the core support made for??? If it's only a 22" opening, a 26" radiator will do no good unless you cut your radiator support to allow the entire radiator to have air flow! Unless it's a car you don't mind cutting, you can and will find a 22" radiator that handles 403hp no problem!! I believe my brother is running a 22" radiator in his 69 Dart with a 416 that's pumping out well over 400hp, no problems in the cooling dept that I've heard!!

The opening is 22 inches but I disagree with your statement. Even if I don't open it up to 26 inches, the extra water capacity isn't a bad thing.

As far as finding a radiator that is 22 inches, this Griffin radiator for a Camaro seems to have the right dimensions for what I need.

The price isn't so bad either. The 1.25 inch tubes should keep it cool I think. I just wish Griffin had schematics of where the hole locations are so I can see if they line up with the holes on the support, otherwise I'd have to drill new ones. I called Griffin and the tech guy said they didn't have that information.

There's another Griffin radiator that seems similar. Don't know the difference between the two.
