Does UNC cross test super score?

I am trying to find out if UNC cross test superstores like Pitt.

So if my son has a 710 SAT CR and a 32 ACT math section, would that count as an equivalent 1450 total score?

I do not think they do that. I have not heard of a university that does. You may always email the admissions office to ask them directly

UNC does not. I do know that UNC-C does but that is the only NC school I have heard of doing that.
