There is no Fox only magazine. Muscle Mustangs & Fast Fords, 5.0 and Modified Mustangs and Fords are all owned by Source Interlink Media and generally offer very little Fox coverage and a lot of the same crap. In their defense, the April issue of 5.0 has a BUNCH of Fox stuff, in celebration of the 30th anniversary of the Fox platform. Also, MM&FF did a "79-93 Mustang Performance" issue last year that was a bunch of rehashed articles from past years and dealt specifically with Fox cars. You can still find it on newsstands if you look around a little. Before they became Modified Mustangs
and Fords, Modified was the most consistent with articles about our cars. It seemed like they made a concious effort to feature one S197, one New Edge, one SN95 and one Fox each month. Since the new format hit, that has all gone away.
Mustang Enthusiast is the only other Mustang rag that specializes in late model stuff and it isn't owned by SIM. They show some Foxes, but they're much more about "show" than "nuts and bolts". You'll see a lot of V6 New Edge cars with a cold air, bagged
suspension and a sound system that will blow the windows out, rather than cylinder head comparo's or blower tech.
Legendary Fords magazine is another independent, but it is aimed at the "classic" crowd.
If you join
the Mustang Club of America you'll get Mustang Times 12 times a year. It's a nice magazine and occasionally features a Fox or two.
That's literally all there is. 5.SLOW may have been blunt, but he's not too far off the mark. I've let my subscriptions to both MMFF & 5.0 lapse after subscribing to both for 10 years. I had just re-upped for a 3-year subscription to Modified right before they changed their format. If it had changed prior to that, I would have let it go too. Enthusiast is "okay" for bathroom material, but that's about it.
