Mopar Has Unleashed Its New 807-HP Hellcrate Redeye Supercharged HEMI Crate Engine


The crate engine designed for classic car restorations.

Mopar is unleashing the most powerful production muscle-car engine ever available to builders and enthusiasts with the launch of its newest crate engine – the 807-horsepower Hellcrate Redeye 6.2-liter Supercharged HEMI® V-8 engine.

The supercharged 6.2-liter V8 is based on the ones featured in the Dodge Challenger SRT Demon and SRT Super Stock and comes rated at 807 hp and 717 lb-ft of torque.

“With the addition of this new supercharged HEMI, Mopar now offers five HEMI crate engines with a range of 375 to 1,000 horsepower,” said Mark Bosanac, Head of Mopar Service, Parts and Customer Care for FCA – North America. “All Mopar crate engines are quality-tested and factory-backed to deliver proven performance to our enthusiasts.”

Rated at 807 horsepower and 717 lb.-ft. of torque on 91-octane pump gas, the new Hellcrate Redeye crate engine is engineered with proven, factory-backed hardware first seen in the wheelie-pulling, record-setting, limited-edition 2018 Dodge Challenger SRT Demon – the world’s quickest and most powerful muscle car ever. This same supercharged HEMI engine powers the industry’s most powerful muscle cars, including the new Dodge Charger SRT Hellcat Redeye, Challenger SRT Hellcat Redeye and the high-horsepower halo of the lineup in 2021, the new 807-horsepower Challenger SRT Super Stock.

The engine is an upgrade from the already available 707-hp Hellcrate and is legal to be used in pre-1976 street cars and trucks without having to deal with the more onerous regulations required when customizing newer models. The Hellcrate Redeye features a 2.7-liter supercharger that runs at 14.5 psi of boost and a 6,500 redline and lists for $21,807 compared to the Hellcrate’s price $20,215. It comes ready for use with an automatic transmission, but a kit to make it compatible with a manual is also available.

The Hellcrate Redeye 6.2-liter Supercharged HEMI V-8 engine (part # 68303091AA) is available to order today. The awesome 807- horsepower HEMI ships in distinctive packaging that features the Hellcat Redeye logo and includes in-depth information sheets with installation requirements and helpful tips. Mopar HEMI crate engines are covered against defects in materials and workmanship for a 90-day period (parts exchange only).
