Hey I could really use some good advice. I have an orange 2004 3.8 V6 stang and I want more power behind the wheels. Ive already put some money into it making it look like a show car, so i dont wanna sell it and buy a GT. So what would be best, to do an engine swap for a 4.7, or to drop some money and soup up my V6. How much would it cost to do an engine swap, and what else would need to be done to it?

Some tuners managed to get much more horse power with a V6 than what a V8 offers with the help of a compressor, NOS or turbos but you can't have the sound and torque of a V8 and you will never get the same mileage with a beefed up V6 than with a V8.
Unless you have a wrecked V8 Mustang sitting in your yard, it will not be cheap to swap from a V6 to a V8. The V8 is heavier so you will need to replace the suspensions and with the increase of power, the transmission and the rear end might not last very long. You will also have to replace the computer and all the wiring.
If some day you decide to sell it you will probably not get the money you invested in it.
If you spent a lot of time and money to make it a show car you might be able to sell it a good price and buy a nice V8 Mustang for cheaper than modifying your V6 one.
Do you have any photos of your car to show us?

Edit
Here is an article explaining how to swap engines. The photos are missing but the text will give you an idea of the work:

I have an 08 v6 and was thinking about a swap to the v8. Around how much would it be?

A swap on a 2008 Mustang? You would have to forget about your warranty and it would cost big bucks if you install a 2008 V8 and parts. Sell your Mustang and buy a V8 one, it will be easier, cheaper and safer.

You should have thought about that shit before you bought a weak 6 banger in 08. Sorry bud, but that was not a real smooth move if you were actually looking for a real Mustang. Give that car to your wife or teenager and go out and buy a real Mustang.
