Description

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 EFI manifold is designed to work with 4150 Style Throttle body EFI systems like the Holley 4150 style flange Universal Throttle Bodies. 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 300-276 EFI manifold includes black anodized fuel rails and rail bracket assortment for an easy installation with the injectors that you choose to use for your combination. The intake manifolds are designed for use with 289-347 cubic inch Small Block Ford engines 8.2" deck height.
