Tired of the Ford Mustang's boring old EcoBoost four and Coyote V8s? The Shelby GT 500 just not making enough torque for you? You're not alone, which is why this YouTuber is putting something a little bit more interesting between the strut towers.

It started with the rebuild of a wrecked 2017 Mustang GT. To get the parts he needed for the build, Westen Champlin bought a 2.3L EcoBoost car for the intact front clip. But what do you do with the rest of your parts car when everything's (mostly) fine other than the missing front end?

You do an engine swap, of course. Not an LS, or even another 5.0L you've found at the junkyard. Been there, done that. Westen's listening to the comments and dropping a 12V Cummins diesel into an S550 Mustang.

A few measurements started the video series, then Westen buys an old Ram with a 12V 5.9L inline-six Cummins diesel to pull for the project.

There's a lot of work between pulling the 2.3 and a running and driving diesel, including a new transmission and some serious power upgrades. And less fabrication than you'd probably expect.

But this is almost it. When the work starts to pay off. The Smokestang has the engine in place, it starts, and in this video, the car moves for the first time. Loudly, with loads of smoke, and even more heresy.

It's one of the most interesting Mustang swaps we've ever seen, or at least one of the most ambitious. Watch the most recent video and you'll probably be looking for the rest.
