Hit the Street FAST with Holley's Dual Plane Intake Manifold
A dual plane design makes this manifold perfect for low-end torque while still reaching up to 6500 RPM. The cast aluminum construction is light and efficient with consistent wall thicknesses and improved casting quality. O-ring cylinder head mounting flange gaskets provide an OE-style seal that makes installation a snap! Minimum carb flange height means the manifold clears the hood with little to no modification.
