LAS VEGAS, NV — A Hellephant never forgets.

We’re pretty sure that’s how the saying goes, but it’s hard to remember when you’re focused entirely on Mopar’s new supercharged 1,000-horsepower, 950 foot-pounds producing 426 HEMI crate engine.

Mopar is calling it the ‘Hellephant’ because they’re mad geniuses.

Fiat-Chrysler officials unveiled the new Mopar crate engine Tuesday at their annual news conference traditionally held at 4:26 p.m. on the opening day of the SEMA Show.

Last year, Mopar introduced the ‘Hellcrate’ engine—a 707-hp powerplant named after the Hellcat vehicles it powers in the Dodge lineup.

The Hellephant engine hits the 1,000-hp mark via bulked-up displacement, with four inches of stroke and bore specs at 4.125 inches. An improved supercharger with a high-efficiency rotor is mounted on an all-aluminum block.

The engine assembly and kit are designed for installation on pre-1976 street and off-road vehicles.

The engine and supporting kit’s Hellephant logo is a nod to the Mopar brand’s past and present, honoring both the modern Hellcat, and the iconic 426 HEMI engine introduced in 1964 which every gearhead knows is nicknamed “the elephant.”

According to the Mopar news release, the complete engine assembly includes a water pump, flywheel, front sump oil pan, supercharger with throttle body, fuel injectors, and coil packs.

The first-ever 1,000-hp crate engine assembly offered by an OEM can be paired with the Mopar Hellephant 426 Supercharged Mopar Crate HEMI Engine Kit for relatively simple plug-and-play by experienced installers, Mopar officials say.

Additional Hellephant features include valve covers imported from the Dodge Challenger SRT Hellcat Redeye and valvetrain, valves, locks, and retainers pulled from the Dodge Challenger SRT Demon. The engine build includes a special high-lift cam, as well as custom-forged pistons.

Mopar unveiled the engine inside a new custom 1968 Dodge “Super Charger” concept vehicle, because they correctly predicted it would be awesome if they did.
