Fiat Chrysler has begun taking orders, through the Mopar order desk, for the 1,000-hp “Hellephant” crate engine unveiled at last fall’s SEMA show in Las Vegas.

Available at for $29,995 US, the Hellephant is a supercharged 7.0-litre Hemi V-8 that puts out 1,000 hp and 950 lb-ft of torque. The plug-and-play engine kit costs an additional $2,265 US. The order desk for the 426-cid engine and kit was appropriately opened on April 26 (4/26), marking the day as Hemi Day.

“The reaction when we revealed the ‘Hellephant’ engine at the SEMA Show was just amazing, and the momentum continued after the show, with close to 1,000 people expressing interest in buying this engine,” said Steve Beahm, Head of Parts & Service (Mopar) and Passenger Car Brands, FCA - North America. “Power and performance are ingrained in our brand’s DNA, and there is no better time to open pre-orders of this 1,000-horsepower, supercharged engine than on HEMI Day.”

The engine assembly includes water pump, flywheel, front sump oil pan, supercharger with throttle body, fuel injectors and coil packs. The Hemi engine kit includes a powertrain control module, power distribution center, engine wiring harness, chassis harness, accelerator pedal, ground jumper, oxygen sensors, charge air temperature sensors, fuel pump control module, CAN bus interface device and detailed information sheets with helpful installation tips.

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

Other parts and accessories to assist the Hellephant build include a Front-End Accessory Drive Kit, A/C Expansion Kit, Exhaust Manifold Kit, Rear Sump Oil Pan Kit and 45-degree Oil Filter (P/N 77072447). Prices are available at

The 1,000-hp mark was breached through an increase in displacement, via a 4.125-inch bore and 4-inch stroke for each cylinder. The supercharger also features a high-efficiency rotor set. The all-aluminum block helps keep the massive engine lighter than a similarly-sized cast-iron unit.
