We love a good engine swap. Whether we're talking about a rotary engine in a BMW M6, a 2JZ in a Corvette Z06, or the five-pot from an Audi RS3 in a Golf R, there's something really cool about changing the character of a vehicle by changing its source of power. Obviously, not everyone feels this way and some consider an engine swap to be sacrilege of the highest order, but that won't stop them from happening. The latest we've come across is one that is certainly uncommon, if not the only of its kind. This 1969 Ford Mustang is now powered by an AMG engine.

The 5.5-liter twin-turbo V8 engine comes from a Mercedes-AMG E63, which in stock form used to generate around 550 horsepower. But that wasn't enough for Anarchy Garage in the UK. After sending the completed build to MSL Performance, the engine now produces a meaty 721 hp and 885 lb-ft of torque. If you watched the above video, you'll know that it wasn't just the engine that the E63 donated to this car either. While the AMG's brakes look great here, we're not sure about the AMG-style vents in the front bumper, or the bumper as a whole.

If the exterior styling has you bothered, the interior may cause you to blow a fuse of your own. The entire dashboard is now that of an AMG, with a Merc key used to start the beast up. The center console is also borrowed from the Merc, as are the seats. The door panels are trimmed in a quilted finish to match the AMG theme, and although the overall look of the car inside and out is controversial to say the least, we have to concede that the shaved engine bay is beautifully executed. You may hate this, but at least after 25 years of sitting collecting dust, this '69 'Stang is now going to see daily use.
