Edelbrock part #46125 Gen III HEMI 426 Long-Block is the base for our Supercharged crate engine, but is also a great starting point for any high horsepower forced induction Mopar build. Its compact design allows for a seamless swap into most platforms; eliminating the need for modifications to your engine bay or hood. The foundation of this engine is a brand new iron Mopar 392 block with a forged and balanced Manley crankshaft, forged Manley H-Beam connecting rods and Manley forged aluminum pistons. The 4.090in. bore and 4.050in. stroke help this HEMI produce incredible low end torque. The 9.9:1 compression ratio allows for safe and reliable supercharged performance on 91 octane pump gas.
