I'm not upset, I just don't know what you disagree with. There was more than one thing on that post that you could disagree with and without knowing what that is I can't say yes or no to your comment. I have probably 15 sets of X heads & J heads right now and have had probably more than 50 sets over time and I don't know what you are saying. If they don't say 360 what do they say? Do you have a picture because I have never seen one. What years?
I know Chrysler have done some strange things, could be casting plant some where, west coast? I'm on east coast so maybe I just never seen one.
