Edelbrock Gen III 426 HEMI E-Force Supercharged Long Block Crate Engines
Edelbrock Gen III 426 HEMI E-Force Supercharged long block crate engines start with brand new iron Mopar 392 blocks. The engines are then assembled with high-quality components, including Edelbrock E-Force supercharger systems featuring Eaton TVS R2650 rotors—which provide unparalleled efficiency, whisper quiet operation, and OEM reliability. A 4.090 in. bore and 4.050 in. stroke help these HEMI engines produce incredible low-end torque, while the 9.9:1 compression ratio allows for safe and reliable supercharged performance on 91 octane pump gas. Edelbrock Gen III 426 HEMI E-Force Supercharged long block crate engines are available with or without electronics (ECU with tune and wiring harness).
