Edelbrock Part # 46720 is the same long-block used on our E-Force 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.Engine Specifications: • Finish: Black powder coated • Displacement: 416 c.i.d. • Horsepower: Upwards of 720 HP when used with Edelbrock supercharger • Torque: Upwards of 695 ft/lbs. when used with Edelbrock supercharger • Compression: 9.5:1 • Block: LS3 Aluminum • Crankshaft: Forged 4340 • Pistons: Forged Aluminum • Rods: Forged H-Beam • Camshaft: 215°/247°, .629/.656, 121 LSA • Rocker Arms: LS3, 1.7 ratio • Cylinder Heads: GM with Edelbrock Valve Springs #5768 • Warranty: 2-year / Unlimited mileage • Long Block only.
