Mopar stays one step ahead of GM/Chevrolet....

Mopar, Fiat Chrysler's parts division, is now taking orders for its 1,000 hp “Hellephant” 426 HEMI V8, billed as the most powerful crate engine ever offered from a major automaker.

To create it, Mopar switched from iron to aluminum for the block, increased the displacement from 6.2 liters to 7.0 liters, added the valvetrain from the Demon’s 840 hp V8 and strapped on a 3.0-liter supercharger, among other updates.
