Matt, you may be right about the 9". After looking at it I thought how it could be an 8" maybe. It does have 31 spline though I know that.
I am going to try and grab the 250 then. Not sure what to put it in though. I have been having second thoughts about the 48 too... I have been thinking about how making it a pro street will take more than 10,000 bucks and just now thinking about maybe getting it built quicker and cheaper for now so it doesn't sit outside still and rot away. I don't wan't to do this because I would really like a pro street but I was thinking of maybe buying another car and making a full out drag car with it like finding a Nova, gutting it all out and just throwing a big block in it and not have it street legal, etc. I am thinking the 48 will be hard to make a drag and street car and take too much money, especially at my age and how I will be going to college in a few months and all.
Not sure though I may still try working towards the pro street thing but we'll see.
