‘Hellephant’ in the Room With 1,000-Horsepower 426 Crate HEMI Engine

Mopar presents the brand-new HEMI®-engine-powered beast: the 'Hellephant' 426 Supercharged Crate HEMI engine turning the crank at a mammoth 1,000 horsepower and 950 lb.-ft. of torque.

Mopar’s exhibit at the SEMA Show (Specialty Equipment Market Association Show) included the unveiling of the 1968 Dodge “Super Charger” Concept. It’s the perfect package for highlighting the ‘Hellephant’ 426 Supercharged Crate HEMI engine assembly and kit.

Our enthusiasts crave power and performance and our new ‘Hellephant’ Mopar Crate HEMI engine and kit delivers huge horsepower and torque in a plug-and-play package that is unique in the industry. The 1968 Dodge Charger is one of the hottest classic cars, which is why we decided to use it as a starting point for the ‘Super Charger’ Concept. It’s an amazing vehicle and a great showcase for our ‘Hellephant’ engine.

The ‘Hellephant’ engine hits the magical 1,000-horsepower mark via bulked-up displacement with 4.0 inches of stroke and bore specs at 4.125 inches. An improved supercharger with a high-efficiency rotor is mounted on the all-aluminum block. This allows for huge weight savings to keep the “Hellephant” light. The all-aluminum block, used in Mopar Dodge Challenger Drag Pak race vehicles, was configured for the street in close collaboration with Mopar and engineers from the motorsports world.

The ‘Hellephant’ logo provides a nod to the Mopar brand’s past and present. The name and logo call out the legendary 426 HEMI engine, first introduced in 1964 and nicknamed the “elephant” for its power and size, as well as the 707-horsepower Mopar “Hellcrate” Engine Kit.


The first-ever 1,000-horsepower crate engine assembly and kit are designed for installation on pre-1976 street and off-road vehicles. 

The engine assembly includes a water pump, flywheel, front sump oil pan, supercharger with throttle body, fuel injectors and coil packs. Additional features include valve covers imported from the Dodge Challenger SRT Hellcat Redeye and valve train, 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.

Dropping in the ‘Hellephant’ is almost turnkey with the ‘Hellephant’ 426 Supercharged Mopar Crate HEMI Engine Kit. 

The kit includes a powertrain control module (PCM), power distribution center, engine wiring harness, chassis harness, accelerator pedal, ground jumper, oxygen sensors, charge air temperature sensors, fuel pump control module and cam bus interface device. The PCM is unlocked and tuned to pump out 1,000 horsepower and 950 lb.-ft. of torque.

The kit ships in unique packaging, featuring the ‘Hellephant’ logo and includes in-depth information sheets with helpful installation tips and requirements.
