Where the 6 speed has the advantage is the deeper overdrive of 0.5:1 so you still keep mild highway behavior even with 4.10s....
In 6th gear with 4.10's you are actually running slightly lower highway rpms than you do with the factory auto and performance(3.07) axle..

Thats about where the calc put it, low 6k range. Sounds like 4:09's are going to be a bit much for me. You guy think a valve spring and rocker change (1.6) will be enough for a L98 to pull to there?
