Any gains to justify the cost of a regear from 3.27 to 3.73?

I currently have 3.27 in my 8.8 and auto trans 5.0. But I also have a set of 3.73 sitting on the shelf. I was about to sell them unless I can find some good positive gains to justify the regear cost to use them. I know in other stangs 2.73 to 3.73 was great but I fear I wouldnt be as happy with the money spent on this.

I would love 4.10's but with my highway RPM already at 2200-2500 (IIRC) at 80 I think 4.10 would just be too high of a cruising RPM

Thoughts? any real world gains experience?
