The 1,000 horsepower 426 cubic-inch ‘Hellephant’ HEMI engine is now completely sold out.

Well, that didn’t take long. After going on pre-sale earlier last week, Fiat Chrysler is reporting that the limited-run of the 7.0-L Hellephant engine is now completely spoken for.

Mopar announced the Hellephant pre-sale on April 26th (or 4/26 HEMI day) with very little fanfare. They probably didn’t need to--the engine was revealed at last year’s SEMA Show in a mindblowing 1968 Dodge “Super Charger” concept, and since then, Mopar fans have been clamoring at the bit to get their hands on one.

And for good reason. The Hellephant is designed to not only offer more power than a Dodge Demon, but it’s also designed to be as “plug and play” as possible with pre-1976 Dodge vehicles. Turning any old Charger or Challenger into a real speed demon is just one Hellephant away.

Sadly, that’s no longer the case. We’re told that the Hellephant actually sold out in just two days, so by the time most people reported the pre-sale (including us--sorry!) the engine was long gone.

“Given the high demand and the hand-built, time-intensive build process, we have closed preordering for the 426 Hellephant Supercharged HEMI crate engine,” an FCA spokesperson told Allpar.com. “Based on pre-orders, the engine sold out in just two days. Customers can visit www.cratehemi.com to receive future information and updates on the 'Hellephant' engine."

Production volume of the Hellephant is unknown, but rumors point to a limited-run of the hand-built engine of around 100 units. We can see why it didn’t take long for it to sell out despite the fact that each engine cost more than a base-model Dodge Charger.

With that insane popularity, though, we’d expect FCA to get to work improving production capacity for people who didn’t get their order in on time.
