Thanks alot guys. The weather finally cleared up so I went around the block a few more times this evening. Even though it's only a 3.90 rear end (the other was a 4.11), I can really tell a difference in speed. The tranny is way quieter too. My next step is to take it out on the main thoroughfare. I want to get it to top speed and see what she'll do....but I got to build alittle more confidence.
