Ok i have a stock 07 v6 mustang. I have found out that it would probally be a good idea to go with a v8, and i have found a used 07 v8 engine but i dont know what all it will take to get it in the car and completely working, im going to list everything it says it comes with, and will you guys tell me what else ill need, also ill give a list of parts i plan on adding.
"Up for auction today is a complete engine drop-out package removed from a 2007 Ford Mustang GT. This 4.6L 300HP 320 lb-ft torque Mustang GT engine dropout includes 5 speed transmission, all engine accessories (starter, flywheel, a/c compressor, power steering pump, alternator) engine harness, pedal assembly, OEM shifter, and main engine computer. Heres your chance to own the complete engine package out of America's most sought after sports car!!"
here is what they say they check on it.
"We thoroughly inspect the motor and then back it with a 6 month warranty minus shipping. We do a compression test on each cylinder. A Mustang GT engine from a roll over vehicle will run "perfect", but if someone tried to start it before the engines top half was properly drained, then there is probably damage. If the oil was not drained, the extra oil in the upper half will cause friction and the push rod most likely will crack in the engine. The motor will still run great, but it will have a dead cylinder. A compression test will show if any of the cylinders have damage.
A vacuum test ensures the engines internals are functional and the engine has a good "vacuum" draw to it. If the engine has a low output of vacuum pressure (in pounds) then we know the engine has internal damage and needs attention or rebuilt.
An oil pressure test is done when the motor is warm and cold. When a Mustang GT engine takes front end shot, it can push the cradle into the oil pan. This makes sure there is no damage to the oil pump or lower internals of the block.
A CO check is done to make sure there is no damage to the heads or block. If a Mustang vehicle takes one on the front of the block it can damage the crank. If the harmonic balancer is even just slightly hit, it can wipe out the whole lower end. The CO check will tell us if there is damage there.
We then will inspect the trans. The trans is shifted through it's gears to make sure there is not any damage. The fluid is drained and inspected as well. If there is any metal or brass shavings in the trans, then the trans is sent out for a rebuild.
Buy with confidence, you will not find a more thorough package than this one on ebay. Here are the stats. We will not list a package until it has been fully tested, and is out of the vehicle. This is the actual package pictured. It is out, tested, and ready to go. Here are the stats:
Seems to me that buying a GT with the motor still in it would be more cost effective, in the end you will probably have more invested in doing this conversion than if you bought a rolling GT. Still though, if you did no mods to the exterior...... Could make for a MEAN sleeper ya know? Unless you got the 4.0 for next to nothin, or it is a salvage or something, I would suggest spending the money on your 4.0 in upgrades/vs this conversion. I mean, I bought my 05 v6 one year ago for 16k, and I have seen 05 GT's selling for that now, soooooo?????? Whatever you decide of course is cool with us, but from a money standpoint, my vote goes for sell your 6 and buy a 8 if that is what you really want under your right foot.
Are you set on keeping the car because it might be cheaper to trade or sell and buy a complete v8 car new or used.
yes do you want to keep the car ?

one act of kindness at a time
if your really looking to spend that much money on power you might as well buy a used gt or drop an even bigger engine than the gt one in there if ur gonna be buying a new engine and you can sell your 4.0 one when your done to maybe make some back
i'd say if you're intent on keeping your V6 body, you may as well buy the SVT Cobra motor..you could just go with a procharger if you wanted V8 numbers, and V6 insurance..but definately do the trade in if you really want to go through all this work, IMO...and i guess the opinions of others..but whatever you do, good luck!
I guess it depends on how good a deal you're getting on the GT engine, but if you're going to swap out the engine I agree it would make more sense to go with a crate engine. You can use the same tranny you already have in your car. Either that or the much easier supercharger install, which could make your car as powerful (or more so in some cases) than a stock GT.

Just estimating...
$5000 for engine + install. 300Hp/320tq (at crank)
$5000 for turbos or charger - slightly over 300hp/320tq (at rear wheels?)
If it were my money, I'd go with the power adder, or buy a new car. Far, far less hassle imo. An engine swap could possibly have countless issues/gremlins, whereas bolting on a charger can be done in a day.
If you really want a new motor, like others said go for a 5.4. You think you'll be completely satisfied with just a stock 4.6?
actually i would be getting the 4.6l gt engine with tranny for a total of 2,900 dollars, and it looks like its in perfect condition, and it comes with a 1 year warranty, and it dosent matter whether i add a supercharger or turbo to it, those dont void the warranty. I would get a 5.4l but i can not seem to find any of the cobra 5.4l engines on the internet for sale.
If my car were an automatic then a 4.6l swap would be in my distant future mods.
The difference between installing a power adder and swapping in a 4.6 is that the power adder will get you the same power as the 4.6 as long as it is stock but the 4.6 has a ton of room to grow. We've all seen the numbers that the GT owners have been making with just an intake/tune and some headers (around 300rwhp)
On top of that, once you install a 4.6 you then have the option of blowing it which would put you into numbers beyond what a 4.0 can reach without a great deal of work.
