Your Rating


Edelbrock part #46720 is the same long-block used on our LS Supercharged crate engine that delivers 720 horsepower and 695 ft-lbs. of torque on 91 octane pump gas. It features an aluminum LS3 block with a forged and balanced Manley crankshaft, forged Manley h-Beam connecting rods and Manley forged aluminum pistons to create a 416ci LS3 stroker with 4.065" bore and 4 stroke. Its compact design allows for a seamless swap into most platforms; eliminating the need for modifications to your engine bay or hood. This long-block is a great foundation for starting any high performance forced induction LS based build.
