Hennessey Performance loves to inject great power into just about anything that has four wheels. The Texas tuner already has plans for a 1,000 horsepower (746 kilowatt) version of the already powerful Ram TRX, namely the upcoming Hennessey Mammoth which was announced earlier this year. For those who just can’t stand the tiny Hellcat 6.2-liter V8, Hennessey now offers another plan. Can you say 426 Hemi?
In fact, Hennessey prefers to say Hellephant Madness. That’s the title of a new video from the tuner announcing this plan, but the engine swap doesn’t stop with the TRX. In the four-minute clip, John Hennessey walks us through the current production schedule for Mammoth’s upgrades before revealing a Hellephant V8 crate engine. and a Dodge Durango SRT. It appears the company bought two Hellephant engines, and with Hennessey being Hennessey, there is now a desire for Hellephant everything.
To jog your memory, in-house parts group Stellantis Mopar released the Hellephant crate engine in 2018. Displacing 7.0 liters (426 cubic inches), it’s a callback to the legendary 426 Hemi V8 that powered a plethora of The Chrysler division’s muscle cars made during the classic muscle car era. The modern iteration packs a supercharger and claims 1,000 hp right out of the box, though there is a catch. Mopar lists the engine as “designed for installation on pre-1976 on and off-road vehicles.” This is presumably for broadcast purposes, so we don’t know how plug-and-play it will be for the TRX and Durango.
In any case, Hennessey says that the swaps will happen and it looks like the project could become a video series. The literal question asked now is which vehicle should go under the knife first. We’re betting on TRX because honestly it seems like enthusiasts just can’t get enough of this crazy super truck. Then again, no one is really talking about the Durango SRT, and there is something to be said for leading instead of following.
Ah, make decisions.
