1,000 hp Hellephant crate engine enters production after quality delay

Sources claim the engines initially had excessive camshaft tension.

Fiat Chrysler Automobiles' 1,000-horsepower Mopar Hellephant crate engine is finally ready to enter production after a technical issue stalled availability.

Muscle Cars and Trucks received official confirmation that the engines will start rolling off the assembly line before the end of the year after the company resolved a quality issue. Separate sources told the outlet that the problems centered around camshaft failures due to excessive tension.
Legal for track cars or emissions-exempt classics, the 7.0-liter supercharged V8 boasts four-figure horsepower and 950 pound-feet of torque -- significantly higher than the Dodge Demon's 840 horses and 770 pound-feet of twist.
The company quickly sold the entire year's allocation of hand-assembled Hellephant engines in just two days despite a $30,000 price tag.
"I can't speak to the delay, but of course with anything we bring to market we want to make sure that it's fully validated and appropriate for customer use," Mopar performance and accessories head Kim Mathers said in a statement.
