I just found out yesterday that when I had the engine replaced they put a 5.4 in it instead of a 4.6. I have a 98 mustang gt. Just wondering what the differnce is.

Just to give you an idea of size here is mine when it was a N/A 5.4 2V w/ adapter plates to run the mustang intake, i also had to notch the hood on the underside just for the JLT because its so tight.Its Wider and Taller then a 4.6

could they have put on PI's from a 5.4?

that would be badass but i dont see them doing that. If so, they just did you a big favor. LOL.

Dude, we really need some pics if you expect us to believe some one just "accidentally" went to all the trouble to swap your 4.6 to a 5.4 for no extra cost.



We are all about to call BULLSh** on this thread.

Yea, I would have to agree with everyone else on this. I wanna see some pics! And if they did, dont take your car there anymore. They would've done you a favor this time, but if they cant tell the difference between a 5.4 and a 4.6, there aint no tellin what they will do next time.

Yea I went to the transmission shop the other day and they accidently tubbed my car. I know the feeling.

This is probobly just a trolling thread to get people all angry and so forth.

Or they thought it would be funny to have 5.4 valve covers on your car so you think they did the swap and you'll go back next time.

I to the shop to take a look at the car and he showed me the engine there were two sensors in the engine that didnt belong in the car that were cut and the 4.6 intake did not fit on the engine and it was rigged to fit. If it is not a 5.4 what could it be.
