HEMI® Day, All Day


The annual celebration of all things HEMI, held on April 26 (4/26) in recognition of the historic 426 HEMI engine which debuted more than 50 years ago and ruled the street and track, roared along throughout the day.


Mopar posted special HEMI-engine-themed content on the brand’s social channels throughout the day, including an announcement from Mark Worman, star of the Graveyard Carz vehicle restoration show on the MotorTrend TV network. Fans could follow and share using special #Hellephant and #HEMIday hashtags.


Worman shared his HEMI Day news via a Facebook Live broadcast at the date-appropriate time of 4:26 pm ET. Mopar also carried Worman’s Facebook Live announcement on the brand’s Facebook page,


The ‘Hellephant’ in the Room


The Mopar ‘Hellephant’ 426 Supercharged Crate HEMI 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. A supercharger with a high-efficiency rotor set is mounted on the all-aluminium block. The choice to use aluminium delivers significant weight savings to keep the ‘Hellephant’ light. 


The engine and kit’s distinctive ‘Hellephant’ logo is a nod to the brand’s past and present, calling out the legendary 426 HEMI engine (nicknamed the ‘elephant’ engine for its power and size), as well as the modern-day, 707-horsepower Mopar ‘Hellcrate’ Engine, revealed at the 2017 SEMA Show


The complete engine assembly includes a water pump, flywheel, front sump oil pan, supercharger with throttle body, fuel injectors and coil packs. The engine can be paired with the Mopar ‘Hellephant’ 426 Supercharged Mopar Crate HEMI Engine Kit for relatively simple plug-and-play by experienced installers. The engine assembly and kit are designed for installation on pre-1976 street and off-road vehicles.


Dropping in the ‘Hellephant’ is almost turnkey with the engine kit, which includes a powertrain control module (PCM), power distribution centre, engine wiring harness, chassis harness, accelerator pedal, ground jumper, oxygen sensors, charge air temperature sensors, fuel pump control module and CAN bus interface device. The kit ships in unique packaging, featuring the ‘Hellephant’ logo, and includes in-depth information sheets with helpful installation tips and requirements.
