Can I drop this into a 2006 Mustang Gt Body? I am looking to completly rebuild the engine of my 2006 ford mustang gt. I will sell the old engine along with all other parts I would no longer need. I would then buy a 427 and drop that in along with a new transmission and everything else needed to run the car like a champ. Now is this possible or am I thinking too far off track and living a fantasy?


  • You are not living a fantasy, It is definitely doable in a GT body considering you will already have a decent amount of the things needed to put this in your '06. I have done this very thing but with a V6 so I assure you it will be easier with yours. Although being "doable" you seem like you understand that there are still plenty of modifications needed to make it work. So I hope I answered your question, and good luck with your build.

just curious would this bolt right into my 87 fox without modifications to the mounts


  • No. There would be some mount, frame, and maybe fender modifications needed to bolt this up to the engine bay. But your pony would scream so I would also suggest doing a full rebuild, including trans, differential, and frame rebuild/strengthening.

Is this a direct fit? Is a direct fit to the 94-98 models or will there be alot of work involved In order to make it fit?


  • This motor is not a direct fit for the 1994-98 SN95 body style. You are most likely going to spend some serious money if you decide to go this route. A smart and easier alternative would be a 427 stroker using a 351ci Windsor small block. You can yield the same amount of horsepower without having to sacrifice space or weight. It will also make it easier to use a fuel injection setup if you want to. Hope this helps.

will this 427 engine fit in my 03 cobra 4.6 how much of a problem will take to install


  • The Ford Performance 427ci 535HP Rear Sump Crate Engine will require a decent amount of components to fit properly in your vehicle. This would be a very intuitive job, and we would recommend an experience speed shop for this install.
