And, yes, it does make the 3 speed act like a six. I run a 4:10 rear but in third over rpm's are 2200 at 70 mph!
The trans/overdrive combo is long (on mine the yoke is just 8 inches in front of the trailing arm crossmember) so you will need a MUCH shorter driveshaft. It will handle more torque than a 700R4 so for me it was a much better choice.
