I saw one the other day, and the guys in the store told me it has a 2003 motor in it. My GTS is in the shop, and I haven't looked at the engine in a while, so I couldn't really tell. The guy who is taking it around to different locations, opened up the hood, but again, I couldn't remember what mine looks like. I started talking to him about it, and mentioned in kind of a question that it's a difference of about 15 cu/in, right? He said, "Oh, no. They have almost 600 in this thing". I asked him if there was any head work done on it, and he said he didn't know, that's just what they told him. I was frustrated, because I had to go to the airport, and couldn't continue the conversation. Is it possible to get that much more displacement out of the motor? I just thought Dodge would send someone out with a little more knowledge about the car. I could be wrong, but he didn't strike me as particularly familiar with them.
