At the end of the day, and at the end of this thread, when all you can point to is the "POTENTIAL" (as in, if you were to ship your mill to Sean Hyland with a blank check and a note that says "push the envelope") of your 4V heads as being the only possible advantage to the outgoing Mach, well then, fine. You can have that point. So where does that leave you in this debate? A little bankrupt I think. It's like comparing two houses, and the only thing that comes out on the "plus" side of one house is that it's got a little more land that would allow you to build another foot onto the back of the garage, IF, you wanted to. I love the new Mach as well. I ride in one to the gym with my buddy every flippin day. It's the best package to-date that Ford has put together, hands-down, and a blast to drive (yes, I've wringed it out). But MAN, is it due for a retirement. No insult intended, I don't don't mean to dig on your cars at all. But even with the subframe connectors he has to crreeep over speedbumps as the car bends and stresses. That chassis is obsolete. I had a TON of fun in my '88 GT convert, the '96 Cobra I had, and I've still got my '97 S351. But I don't think that these "comparison" threads really have any basis, it's a foregone conclusion. But you don't have to be defensive about your Machs, I think everybody here has stated their respect and fondness for them...
