some guys on brad's forum seemed to have some good ideas... use this "LX" to clear out the 260 hp 2v V8s for under 20k, then the next year upgrade it to the 3v, perhaps slightly detuned but in such a way that hardcore enthusiasts could easily adjust it back (timing adjustments, etc). To keep it under 20k it would have zero options except transmission... even that might have to be a manual. With leftover 2vs and the volume of 3vs being produced in the upcoming years, it could stay under 20k...
I am forgetting, did the Fox LXs have the exact same V8 as the GTs or did Ford rate it slightly lower?
The Mustang GT guys probably wouldn't complain because they'd actually get to ride in some comfort, which... being that the average GT buyer is a middle age male with plenty of money... is a necessity to many/most of the GT buyers anyway. So it might not cut into GT sales as much as you'd think.
That said, I still doubt its happening.
