Mopar has announced plans to prove their off-road prowess at 2014 Griffin King of The Hammers race in California.

In order to do this, the company has outfitted six “4700 Spec Class” vehicles with the company's 5.7-liter HEMI V8 crate engine. Specifications were not released but Mopar says all the models are loosely based on the Jeep Wrangler and have a tubular chassis.

According to Mopar CEO Pietro Gorlier, "The 5.7 crate engines we are providing are the off-road race version of the recently announced Scat Package performance upgrades for the Challenger and Charger. This event is in essence a proving ground for our engine, set-up, calibration and parts, as we don’t just design and produce quality parts, we want to test them in the field so that customers know that they are getting the very best available.”

The Griffin King of The Hammers off-road race takes place in Johnson Valley and is described as the "toughest one-day off-road race in the world." The course spans more than 100 miles (161 km) and covers terrain such as "sandy washes dotted with creosote bushes, flat dry lakebeds, sand dunes and, of course, the world-famous rock canyons and trails from which it derives its name."
