8-3/4 Vs Dana60 Vs 9" Rear

It seems some guys just have better luck with the 8-3/4 then others. I know a few guys on this board that nuked there's running anywears from 11.80s to 11.10s.

My future plan are to add a 4" crank kit to the car, Not so much to make more power but more for driveability and Ive been thinking of doing a 4-speed swap at some point.
