Going to bump this. Wanted to share what I’m experiencing with my setup:
I sent in my oil sample to Blackstone -- those folks are just great -- awesome service!
Here is my report:

Can't argue with that!
I can go to 4000 miles on the oil and running the oil temps up to 270° is not impacting anything -- that is fantastic news!
Looks like the DT40 and ACDelco UPF48R is the ticket for my setup!
Next time, I'm going to send out a transmission and diff sample with the oil and see how that's doing.
Very excited about the findings...
Oil temps max on a 110° track day was 273°.

My cooling is working very well..
