I got mine in the mail today (it was a birthday present) and I am very impressed with it. I have never really had a stock motor (I usually race mod) that is even worth using but since I will be racing at a place that only runs stock I thought I would ask for one for my birthday and this thing is much faster then my other stocker. It had great torque and and plenty of topspeed I have no way of comparing it to a worthy stock motor though so I dont' really know how much faster it really is. This was just up and down my street so I can't wait to get to the track and actually test it out....
