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.

  1. Great to see the Elephant Heritage continues and Mopar past and present shown there respect for acheivements reached.As
    with other Crate OEM Motor Packages marketing to Restorations Business’s established such as Year One and Classic Industries… Will that be same strategy starting out ? If so where do you think it will start around $25,000 ?

    I appreciate hearing before others in my community since I am loyal MOPAR

    Sincerely thanks have a great day !!!

  2. Let me start by stating that I bleed Chevy Bowties, but even this has me excited. FIC has hit a grand slam homer again by offering such an iconic engine with the newer technology, job well done! And that SuperCharger concept vehicle needs to cross the auction block at Barrett Jackson Scottsdale.

    I like the “relatively simple” part…

  4. Lyle Thomsen says:

    If it has a lot of horsepower,then I’m all for it! My nephews son bought a new Hellcat,and I am very impressed with that. This new engine is incredible! The fact that it comes direct from the factory,says something (in a big way) for Mopar. I myself, am a Corvette guy,have been since high school in the sixties,but I always loved that big “Elephant” engine stuffed between the frame rails of the Mopar cars. One time in my life I owned a Plymouth Savoy with a factory built with ceramic coated headers 426ci wedge motor. Very fast and I’ll never forget the thrill I got every time I punched it! I can’t wait to get a ride in someone’s car that has this new engine in it.

  5. Ira Johnson Jr says:

    Would this fit in a 2013 Challenger

  6. Brett Connolly says:

    I have just purchased a 1969 Charger after years of loving them and wanting one. It just so happens that it has no motor or trans, this is the engine that I want to have for my project! My questions are many but I will start with two. When are these available for purchase and what modifications are required to the chassis in order to be able to handle this engine and all that torque?

    Chrysler should revive the A925 project as a replacement for the hellephant Hemi design… The Dooms Day Design would be well accepted in race circles DOHC engine design
