Cummins-Swapped Mustang Gets a GT500 Body, Because Why Not?

As if the idea of a coal rolling Cummins-swapped Mustang wasn’t enough, this one gets some fresh bodywork, too.

We’ve seen plenty of engine swaps in Mustangs over the years. Some of them have been rather cool (think Predator and Coyote), and some of them not so cool (read: LS). Then there are the swaps that make you scratch your head in bewilderment. That’s certainly the case with YouTuber Westen Champlin‘s Cummins-swapped Mustang, which has been raising eyebrows across America recently.

Champlin is, by nature, a diesel truck guy. So on the surface, it makes sense that he would go the oil burner route in his car build. But as you also might imagine, building a Cummins-swapped Mustang isn’t exactly what one might call an easy task. This job was fraught with issues from the start, including major leaks and fitment issues.

Of course, this coal rolling Mustang isn’t the first such creation on earth, but it is one of the wildest. In fact, Champlin says that after posting a video of the car on Tik Tok, “it got millions of views in the first two days, and everyone’s like ‘what kind of creation is that?'” That response only encouraged Champlin to up the ante, which he accomplished by installing a GT500 front end on the car.

The goal of such a move is to of course get even more attention, and achieve Champlin’s goal of having a million subscribers. “Guys, I live in the middle of nowhere,” he says. “I’ve been quarantined my whole life. Actually, it kinda makes sense why we’re building stuff like this now.” Plus, the car was lacking some bodywork to begin with, so he had to put something on there. So why not GT500 inspired pieces?

Thus, Champlin moves forward with his installation, which is narrated in a rather humorous way. After successfully installing the radiator, for example, he says “It doesn’t hit. I’m just gonna say that I’ve made it this way. This was my plan the whole time.”

The end result also looks pretty cool, we must say. And in case you were worried that Champlin ruined some nice GT or something, he notes that this was a wrecked EcoBoost that was essentially saved from the scrapyard. The next step? Figure out how to make a hood fit, which will undoubtedly require some creative cutting. But who are we to doubt this man on a mission at this point?
