Key Features of Edelbrock 46736 LS 416

• Pro-Flo 4 XT EFI System: Arrives equipped with a high-flow electronic fuel injection intake manifold designed specifically for large-displacement LS strokers.
• Forged 4.00-Inch Stroker Crank: Stretches the factory LS3 displacement out to 416 cubic inches for violent low-end acceleration off the line.
• CNC-Ported Cylinder Heads: Maximizes port velocity so the massive aluminum cylinders can breathe deeply all the way to the 6500 RPM redline.
