Hey Everyone I do apologize, I know I do not have a Mustang, however from the post I have been reading, this forum seem to have the best and the closes answers to what im looking for.
To Start I have a 1999 Lincoln Navigator that has a 5.4L 4V 330 DOHC.
What in looking to do is add a GT500 Lower intake and supercharger. I found a Lower, that is meant for the GT500, however I was told from a couple of "Supercharger Specialist", that it would not fit. However again See attached photos, the Stock Lower and the GT500 Supercharger intakes look pretty close, The two things that seem different are the 2 back coolant ports, on the 5.4L the back ports on the block are plugged, with the GT500 Lower they are open.

So my question is would the GT500 Lower line up? I know its not going to be a bolt on and drive, however would it be possible?

Thanks in advance.
