I wanted to know could I swap a Ford Racing 427ci 535HP Rear Sump Crate Engine into a 1999-2004 Mustang gt without any major problems? Im planning on buying this mustang and it has high mileage and I wanted some hp so I wanted to but this engine and have a mechanic to install it. The only problem im having is I have read online that for a lot of cars engine swaps can be expensive because the motor mounts might not be set up correctly and a lot of welding could be involved. Im not trying to spend a ridiculous amount of money on getting this installed. Also what could I expect to pay for an engine swap such as this one.

First, we only recommend direct fit parts. Aside from that, anything can be done. However, mounts, wiring harness, computer, basically, everything needs replaced. After that, I'm not sure the trans will bolt up for you. Finally, will it pass emissions is an additional question.

Where I live I dont have to worry about emmissions.
Edit:i meant 1994-2004.
Also on american muscle. Com where the engine is sold I think it would be a direct fit because it was under the 1994-1998 mustang parts. ANd when you say everything replace how much money are we talking and why would everything need to be replaced? I was planning on getting a new trans anyway because the engine is over 500hp

Just to add, you will need a front sump set up for the mustang. You can get the correct oil pan and oil pick up tube for this.
I have done many of these projects and they are time and material only. It starts out with about 20 hours up front and then it is by the hour from there. I have done some that take 25 hours and some that took a lot more. The end result is impressive but you need to have the resources to do it right.
