The release of the Hellcrat will be followed by the unveiling of additional high-profile news during the brand’s Mopar SEMA product presentation, scheduled for Tuesday, Oct. 31 at 7:26 p.m. ET/4:26 p.m. PT.  The product presentation can be viewed live at

“Never before has a supercharged, factory-direct 707-horsepower crate engine kit been offered, and we are proud to be the first to deliver a solution enthusiasts have demanded,” said Pietro Gorlier, Head of Parts and Service (Mopar), FCA. “This ultimate powertrain option fits the needs of owners and fans who demand iconic performance.”

The new Mopar Hellcrate HEMI Engine kit provides relatively simple “plug and play” with the 6.2-liter supercharged Crate HEMI Engine assembly — also available from Mopar.

The PCM is unlocked and set to the factory 707-hp calibration. The Hellcrate is optimized for use with manual transmissions, such as the Tremec Magnum transmission kit.

An essential Front End Accessory Drive (FEAD) Kit, which includes an alternator, power steering pump, belts, pulleys and more, is among additional engine accessory hardware components available to assist in installation.

The kit, intended for pre-1976 street and off-road vehicles, ships in unique packaging featuring the Hellcrate logo and includes in-depth information sheets with helpful installation tips and requirements.
