Not for one second during our Mustang Shelby GT500 review did we feel the need for extra muscle. And since the 5.8-liter Trinity is already blown when it leaves the factory, we considered that chapter closed.
Unfortunately, we can't say the same about the owner of the 2013 or 2014 Shelby GT500 in the images below. Perhaps on a mission to spill Hellcat blood, the man ended up spilling his V8's oil, as he blew the engine... the wrong way.

It all started when the Shelby owner aimed to take his muscle car from 662 to 700 hp. And while that might seem odd, especially given the solid rear axle found at the back of the ex-gen Mustang, certain aficionados might find the move legitimate, given the kind of firepower the yet-undelivered 2017 Camaro ZL1 packs, for instance.

However, the Ford guy did the kind of mistake we might expect from teenagers racing under a rock, as he reportedly went for a "cheap internet tune" (laptop tip to Redditor BoogLife for the story).

As you'll be able to see in the pics at the bottom of the page, the SVT V8 is no longer capable of internal combustion - with at least two holes in the engine block, that seems like the reasonable conclusion.

The GT500's 350ci motor can be ordered online, but that would mean paying $30,000 plus swap labor - we'll take the time to remind you a brand new 2016 Mustang GT comes with an MSRP of $32,392.

Sure, the man can always go for a new block and a rebuild, but even so, an iron version would bring the costs to around $15,000, while an aluminum incarnation should see him spending $20,000 on the task - the labor is probably included here, but this doesn't make the situation less cringe-worthy.

Remember kids, always go for a dyno-infused tune when playing at this level of performance.
