Dodge Charger 1968 with a 707 HP Hellcat Engine!

This 1968 Dodge Charger isn’t running a period-correct big-block – it’s powered by a genuine 707-horsepower Hellcat engine pulled from a 2015 Charger SRT. It’s regarded as the first running, driving example of this exact swap. Here’s what it took to fit six decades of engineering into one classic body, and why builders keep repeating the formula.

The very first running, driving vintage muscle car powered by a 707-horsepower, supercharged, 6.2L Hemi engine from a 2015 Dodge SRT Charger Hellcat!

Dropping a modern supercharged engine into a 1968 muscle car sounds like sacrilege to some purists – until they hear it actually run. This particular Charger isn’t just wearing a Hellcat badge for looks; it’s the very first running, driving example of its kind, built around a genuine 707-horsepower engine pulled from a 2015 Dodge SRT Charger Hellcat. That combination didn’t exist on any factory order sheet in 1968, which is exactly what makes it worth a second look. What went into making a 6.2-liter supercharged Hemi fit inside a decades-older body says a lot about where the restomod movement has ended up.

707 Horsepower, Six Decades Apart

The 6.2-liter supercharged Hellcat V8 is rated at 707 horsepower and 650 lb-ft of torque straight from the factory – numbers that would have embarrassed anything on the street, let alone in a showroom, back in 1968. Builders around the country have since repeated this exact swap in other Chargers, some producing even more power once paired with aftermarket supercharger upgrades or dressed with modern eight-speed automatics in place of the era-correct three-speed.

Why the Restomod Formula Keeps Growing

Pairing a modern Hellcat crate engine with a classic body has become one of the most popular restomod trends going, because it delivers vintage styling without sacrificing drivability, reliability, or straight-line performance. Builders typically route power through upgraded rear ends, driveshafts, and brakes to handle the extra torque, turning a car that once struggled to keep up with modern traffic into something that can outrun nearly anything else at a stoplight.
