Mopar Performance 426 Supercharged Crate HEMI Engine

The Hellephant is loosely based on a standard Hellcat engine, but a bigger bore and stroke bring displacement up from 6.2 to 7.0 liters. The Hellcat's iron block is ditched in favor of the all-aluminum block used in the Dodge Challenger Drag Pak race car, helping save significant weight. A new supercharger makes an appearance here, as does a set of custom forged pistons and a high-lift cam. The valvetrain is borrowed from the 840-hp V8 used in the Dodge Challenger Demon.

The Hellephant is the first 1000-hp crate engine to be offered as part of a plug-and-play kit for pre-1976 vehicles. On top of that, Mopar will offer a "Front End Accessory Drive" kit, which includes an alternator, power-steering pump and all the belts and pulleys you may need.

To show off the Hellephant, Mopar installed one in a 1968 Dodge Charger it's cleverly calling the "Super Charger." In the Super Charger, the Hellephant is paired with the stock six-speed manual from a Challenger Hellcat, and there are other modern parts found throughout to give it a modern look.
