The only reason it was not in stock when it came out, there was no weight break for it to fit into. There was no FS/AA class. I don't know, but i don't think the 5.4 combo is better than a 5.2 just because the sc is bigger. I also don’t think most will agree when you say most will agree...duh. Its in the guide so I don’t know what your point is. This thread is about ford giving then taking it back for un know reasons. I wish someone from ford would come on here and tells us why, is that to much to ask.
