difference between 4.6 and 5.4

oannamarie · Dec 4, 2009

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.

That funny:shitbrick they didn't put a 5.4 in. and they would know the difference. Do you see this on your car. no,than,NO

I highly doubt they accidentally put a 5.4 in your car.

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

Im not sure what they put in. The valvue covers have 5.4 on it. A 4.6 intake manifold which is what I am trying to replace will not fit on the engine.

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.

Happens to me all the time. I took my car to the shop last week to get my alternator replaced and they put a Vortech in place of it. Sons of Beetchs!
