This site is dedicated the steps, challenges and victories in retrofitting a Ford Racing  X-Head 427 engine into a 1994 SN95 Mustang GT.

In short:

• YES, the Ford Racing M-6007-X427FRT 450 HP/520 ft-lb engine does fit into a SN95 Mustang
  
• YES, both the engine and the Mustang require modifications…you will not have to use a cutting torch/welder to get the engine to fit
• Yes, if you modify one thing, you’ll find that you have to modify two other things that you never thought about
• YES, you will send Summit Racing and Jeg’s a lot of money…they will become your best friends
• YES, there are many ways to tackle this project…some ways require more money than others
• YES, part vendors advertise that their parts will fit the SN95…sometimes they don’t
• YES, some vendors will send you defective products…you will learn to check parts before installing them
• Yes, eventually this site will answer: How can I do a 351W engine swap in a SN95 Mustang GT in less than 1,721 steps

I hope to to give give all builders the benefit of my experience … hopefully you will save some $$$ and a whole lot of whiskey.
