Default 3.9 diff manual 5l

Anyone running a 3.9 gear set with a manual 5l?
Just wondering how the 5l likes 3.9 gears is it too much for the motor, stock gearing sees 100kph in second gear and I am looking to get the old girl moving a bit quicker.

I've had them in 2 manual v8's and they're great.
Best mod don't bother with 3.7

Great for working out your RPMs at different speeds.

I had them in my old ute.
It was awesome.
Could blow the tyres off it at will but sat on only 2450 at 110.
