Difference in 93 F150 5.0 to 89-93 mustang 5.0

i have a 92 F-150 with a 302 in it. I installed the comp cams c=computer controlled cam. since the f-150's are maps not mass air flow. I installed shortie headers. i have heard that mustang headers work but you have to modify the y-pipe a lot. i bought a bassani off road y-pipe and a flow master dual exhause cat back. basically it is a 2 1/2 off headers to a single 3 inch then to 1 muffler then a dual 2 1/2 out of muffler. The 302's are rollerized. and you can use a mustang intake you just have to plumb the air cleaner diferently. they both have e-7 heads. there are mass air flow conversion kits out there for these trucks. might be worth looking into if you want more cam.
