    All I know is they are listed at the MAC site as 351W conversion shorties for a Fox body. I was hoping someone else had actually tried them!

      Warranty certainly seems better than BBK... coating failed after a year for me

      *Edit: i see it excludes surface rust. I don't think ceramic coatings last at all.

      If I were to redo this I would make some 302 Stainless headers work and extend/change the h-pipe to work

        That’s what I was saying, welding req’d. For some reason, I was thinking that the ‘05-‘11 had physically larger diameter axles, which they don’t. That swap wouldn’t be worth it to the OP now that I remember that. Excuse the brain fart!

          I had midlength mustang headers on my 351, it required cutting several tubes and altering how they run in regards to the steering shaft
