Most engine swaps lurk under the hood of hardcore, drift-prepped JDM sports cars or immaculate, powerful restomodded American classics. But what about the entirely overlooked sleeper category, where average, boring cars receive powertrain upgrades to make them wolves in sheep's clothing? Well, perhaps part of the blame can be laid at the feet of social media, since sleepers don't exactly photograph well. However, those who love the combination of understated looks with magic lurking beneath do have their own community, as proven by a Coyote-swapped Ford Fairlane build that's the subject of the YouTube clip below.

Incognito Fun

In a lengthy post on Power by the Hour Performance, this Fairmont's owner, Fred Felt, gets a chance to show off what's going on underneath a car that can arguably be considered one of the most boring in the history of the automobile. Certain to turn absolutely zero heads, the Fairmont nonetheless is worthy of a second look thanks to the work that's gone on beneath its tired steel.

Under The Hood

The heart of the build is a 5.0-liter Coyote V8 sourced from a 2014 Ford F-150, which has then received a host of upgrades including a Gen-1 Mustang's intake cams, timing cover, and harmonic balancer. It also benefits from a 1996 Mustang Cobra's alternator, power steering pump, and A/C compressor. That cold-air intake comes courtesy of JLT, while the engine was custom-tuned by Palm Beach Dyno.

Plain As Plain Can Get

The interior keeps up with the plain-Jane exterior, though an aftermarket shifter does stand out a bit thanks to some less-than-tidy wiring. It's a Winters unit, which controls a 1999 Mercury Grand Marquis automatic four-speed equipped with a lockup converter and transmission fluid cooler, routing power to the rear end through a three-inch steel driveshaft. All in all, the build looks perfectly put together—though very few people on the street might realize it.
