This post is useless without photos..... 'cause there was never a 5.4L installed in a Mark VIII. :D

And if they say it is a 5.4L and it has a stock Gen I, Gen II, or Cobra intake on it, then it is most likely a 4.6L. (Is anyone making adapter plates for a 5.4L DOHC to use a 4.6L intake?)

To my knowledge, there is not a single intake that will fit a 5.4L under the hood of a MN12/FN10. Then there’s the issue of exhaust… :beek:

But you never know…. Let’s not forget they guy with the “pre-production” Cobra engine with the smooth intake top. :D

There were pictures of a 5.4 DOHC sitting in a MN-12 linked from TCCoA somewhere. I can't find 'em now. It did set right down into the engine bay but the valve covers were millimeters from the shock towers and I don't think headers were on yet. It was also going to require custom fabbed headers since there is so little space in there.

but is it worth the trouble...:rolleyes:
I wasn't commenting on whether it would be worth the trouble. Just that it is possible. Not likely... but possible.
