Radiators: Is 22" enough for 400 HP?
I noticed that the 2nd Griffin PN posted does not have a bung for a drain petcock, and the brackets are a bit different. Neither has a trans cooler.
Interesting... the extra water capacity of a 26" wide rad will be there to absorb transient temperature increases, but will hardly cool any better for long term heat loads from the engine if there is no the air flow over the extra 4".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.
