The Z51 is a road race trans it may have closer gear ratios and hence needs a steeper final drive to offer the same overall performance… not MORE performance
3.24 x 3.62 = 11.73 and 3.14x 3.8 =11.93 that is sub 2% right??? or 1 MPH difference per the same engine RPM...
5 HP is for a muffler valve IMO

Most likely it has the same ratios besides the final drive. The FD difference is all GM has mentioned for it as well as far as I've seen.
And there would be zero reason to change ratios to offset the shorter final drive. Literally no reason. If they did so why bother changing it at all...
