Yes it's stock gear. I have a 4.10 sitting in my garage and even after all these years of reading on this forum how great they are I just can't get myself to do the swap.
As for traction, many of my friends have offered their drag tires to try at least a run but my intention was never to build a drag car. I just didn't like losing to 350Z's so decided to add some bolt-ons. Pretty happy with the results.
Thanks for the feedback guys.
