Mopar adds 807 hp Hellcrate Redeye to crate engine menu

Leave comment

Mopar will now offer its 807 hp Hellcat Redeye V-8 as a crate engine, placing it between the existing 707 hp Hellcat and 1000 hp 426 Hellephant in the hierarchy of supercharged Mopar crate engines.

Compared to the 707 hp Hellcat engine, the “Hellcrate Redeye” uses a larger supercharger, 2.7 liters versus 2.4 liters. It enables more airflow and up to 14.5 pounds of boost. The Redeye is also able to wring more power out of its 6.2-liter displacement by revving to 6500 rpm, 300 rpm higher than the Hellcat. Chalk it up to specially heat-treated journals on the forged-steel crank, improved valvetrain oiling, and double the flow from the oil squirters that spray the bottom of the pistons for cooling.

Out of the box, the Hellcrate Redeye is set up for use in front of an automatic transmission and will have everything from the throttle body to the oil pan. Mopar offers a front accessory drive that adds an alternator, power-steering pump, and the necessary pulleys and belts to help make the installation easier, as well as the flywheel, clutch, and pressure plate for those with manual transmission aspirations. It seems, however, that buyers will still be on the hook for an ECU and wiring harness. The Hellcrate Redeye has an MSRP of $21,807—a fair chunk of change—but on a horsepower-per-dollar metric it’s a bargain when the standard 707 hp Hellcrate is priced at $20,215.

For those with more modest power goals in mind, Mopar also offers a naturally aspirated 5.7 liter Hemi with 375 horsepower and 410 lb-ft. of torque as well as the 6.4 liter Hemi with its 485 horsepower and 475 lb-ft. of torque. Either of those would prove ample power for a restomod muscle car, and the 6.4 liter in particular really sounds the part.


With RB blocks becoming harder and harder to find, Mopar really is making a good case for its crate engines to be a viable solution for repowering classic muscle cars. They’ll never look as cool as a Gen III Hemi, but you can’t knock the performance and drivability.
