T45 or 3650? Also what did you mean by high RPM power loss?
Likely the result of you being higher in the power band at the same speed and being past peak torque so you don't feel the same down low punch. Gears are really felt off the line vs. roll racing speeds.
3650 should put you on 2700rpm at 74mph.
Crunching some numbers:
Based on 2500 RPM with 4:10s = 2275RPM with 3:73s=2165RPM with 3:55s and 2000RPM with 3:27s
How much for the 4.10's and what brand?
