swapping early 3.09 1st into later case

OK, I forget that some of you guys are drag-racers.
The 5.38s and 3.09 team up to be a 13.08 starter gear, corrected to a 24" tire. I get that.
And the 4.10s with the 3.09 make an 11.26 starter-gear,corrected to a 27" tire.
So I get how this could be useful in your case
