I just bought one, but it won't be in use for a while yet. I got the street dist w/vacuum advance, I don't know if the other one is the same internally or not. They told me the one I got is not tuneable, so you get what you get. He said they are typically all in by 2400 and have 24 deg of mechanical advance. If I don't like it for my GTX, I'll swap it to my Chrysler.
