Currently I only have the stock differential in it, and yes it needs steeper gears (I knew this and it's in the plans, but wanted it on the road first.) that being said it is a vast improvement from the 4 speed auto. Here is the trans gearing:
1) 4.46:1 2)2.61 3)1.72 4)1.25 5)1.00 6).84 Rev)4.06

As far as how it drives, I was building it with the possibility of selling it once complete, but after driving it, it will stay in my collection for a long time coming. Don't get me wrong there is lots of room for improvement, but it is the most enjoyable ride I have owned, and now I have a lot more plans for it in the near future, hopefully... But first up is the rear diff(I have the list of diffs from the different models somewhere, I just have to find it, and then also find the right donor,) and a garret t25/t28 hybrid.

Awesome work!

Please post when you locate the list as I'm looking for a donor also for a 2.5 that's received the traditional 5-speed swap.
