A rare Hellephant 426 crate engine is going to the Mecum Auction, in Houston, on April 2, 2022. This supercharged engine was originally offered by Dodge for $29,995. A plug-and-play engine kit was also offered for $2,265. The 426ci Hemi has 1,000-horsepower and 950 lb.-ft. of torque. To squeeze those kinds of monstrous figures from the Hellephant, Mopar lengthened the aluminum block's stroke to 4.0 inches and increased bore to 4.125 inches. Capitalizing on the greater displacement is a supercharger with a high-efficiency rotor, which allows for more oxygen molecules crammed into each combustion chamber on the intake stroke.
