To simplify our pursuit for horsepower, Mopar has released a new crate engine that it lovingly calls the ‘Hellephant’ at this year’s SEMA Show. The motor is essentially a HEMI 7.0 litre (426 cubic inch) supercharged V8 that makes 1,000 hp and 1,288 Nm of torque, with the company saying the engine kit “allows for relatively simple plug-and-play performance.”

The Hellephant is based on the standard engine used in the Hellcat, but with a bigger bore and stroke to increase its displacement. Other revisions include an all-aluminium block from the Dodge Challenger Drag Pak race cars in place of the iron block; special high-lift cam; custom-forged pistons; valve covers from the Challenger SRT Hellcat Redeye; and valve train, valves, locks, and retainers pulled from the Challenger SRT Demon.


Mopar says the complete engine assembly includes a water pump, flywheel, front sump oil pan, supercharger with throttle body, fuel injectors, and coil packs. On top of that, an optional “engine kit” makes the plug-and-play experience even easier, especially on pre-1976 street and off-road vehicles.

The kit includes a powertrain control module (PCM) tuned for max output, power distribution centre, engine wiring harness, chassis harness, accelerator pedal, ground jumper, oxygen sensors, charge air temperature sensors, fuel pump control module and cam bus interface device.


There’s also a Front End Accessory Drive (FEAD) kit, which includes an alternator, power-steering pump, belts, pulleys and more, and is among the hardware components available to make the Hellephant run at its best.

To showcase the new crate engine kit, Mopar installed one in a 1968 Charger, transforming it into the ‘Super Charger’. The ‘De Grigio’ Grey Metallic concept exemplifies the retro modern look, and rides on staggered wheels (20-inch front and 21-inch rear), while six-piston Brembos are present to help slow things down. Oh, the Hellcat’s stock T-6060 six-speed manual transmission sends power to the rear wheels here.
