I saw one a couple of years ago running at the Memphis school. Not sure, but I think I remember it being from that region, or the St. Louis region. As the guys stated above, you have the choice of either engine, plus the coil over rear end (still solid axle). Some guys say that you can get more HP out of the Naps Z motor. But I doubt that you are going to be more than mid pack with that car.
