Temps climbing in 318

Capacity or flow.

But I would think that a new radiator, /6 AC (heavy duty cooling), should keep up with a mild 318.

Does the spring in the lower hose run the entire length of the hose?

Temp doesn't want to come back down after getting hot and then slowing down again, so probably not the hose is what I was thinking.
