HOLLEY 4150 SINGLE PLANE CARBURETED INTAKE MANIFOLD
Carbureted Single Plane Intake Manifold Small Block Ford 289-347
Part # 300-277
The new single plane intake manifolds are designed to provide a broad RPM powerband for high-performance street/strip engine applications to a maximum engine speed of 7500 RPM. The carbureted manifold has a 4150 flange to work with all mechanical secondary square bore carburetors. These intake manifolds are designed to accept most stock hardware and accessory brackets, but offer performance features like better plenum and runner geometry for improved charge airflow. The isolated design of the air/fuel passages helps to increase charge air density and performance. The intake manifolds are designed for use with 289-347 cubic inch Small Block Ford engines with a 8.2″ deck height.
