crown vic question
 

are most performance parts inter changeable between the 4.6 mustang and the crown victoria

I have found a good number of the parts for the GT of the same year as the Vic in question will work. Their are a few differences on some things, but not a great deal. What are you looking at doing? Heads and intakes should match up as long as you match them when replacing without bolt up problems. :postwhore:

ok i just want to do exhaust and intake for now. it's only a daily driver

A CAI will likely be a little different due to layout of the motor, but by how much is uncertain. Exhaust won't be the same as there is a little longer length to the crown over a stang. With that said, the diameter of the pipes should be the same at 2.5 or whatever you decide. X-pipes will likely be close but make sure before you buy one.

you can use the same shorty headers but long tubes sadly no. I am pretty damn sure the h-pipe off a stang will not work with that body platform. other things like heads,cams,pulleys etc.. work (your manifold is different though so i am not 100% sure on Throttle bodys).

u don't live in Deltona FL do u? I know I guy down here always talking about putting Mustang parts on his police intercepter crown vic.
