Well I believe the 3.91 would be great but only if you run the 7500rpm redline. Can you do that redline with the SC?

If so then for sure do a 3.91 with LSD. Your shift points at 7500 would not be bad at all the 2-3 shift will be around 58-59mph, 3-4 shift like 92-94mph. About the same as 3.73 rear diff with stock redline.
