Product Details

This is the Edelbrock part #46125, a 426 cubic inch Gen III Hemi Long-Block engine. It's designed as the base for Edelbrock's E-Force Supercharged crate engine but also serves as an excellent starting point for any Mopar build aiming for high horsepower, especially with forced induction. Its compact design is a notable advantage, allowing for a straightforward swap into most vehicle platforms without requiring modifications to your engine bay or hood.

The core of this engine is a brand-new Mopar iron 392 block. Inside, you'll find a forged and balanced Manley crankshaft, forged Manley H-Beam connecting rods, and Manley forged aluminum pistons. The bore measures 4.090 inches and the stroke is 4.050 inches, which contributes to generating impressive low-end torque. With a 9.9:1 compression ratio, this engine is set up for safe and reliable supercharged performance when using 91 octane pump gas.

The engine comes equipped with Edelbrock Performer RPM cylinder heads (#61099) and stock Gen III Hemi rocker arms. It features a camshaft with 226 degrees of intake duration and 234 degrees of exhaust duration, a .619-inch intake lift and .612-inch exhaust lift, and a 114-degree lobe separation angle. Please note that fuel injectors and a supercharger are not included with this long block. This engine carries a 2-year warranty with unlimited mileage.
