The newly designed single-plane intake manifolds are crafted to deliver a wide RPM powerband for high-performance street/strip engine applications, reaching a maximum engine speed of 7500 RPM. Specifically tailored for 4150 Style Throttle body EFI systems such as the Holley 4150 style flange Universal Throttle Bodies, these intake manifolds seamlessly integrate with most stock hardware and accessory brackets while offering enhanced plenum and runner geometry for superior charge airflow. The isolated design of the air/fuel passages contributes to increased charge air density and overall performance.
The 300-276 EFI manifold package includes black anodized fuel rails and a rail bracket assortment, facilitating a straightforward installation with the injectors of your choice for your specific combination. Engineered for use with 289-347 cubic inch Small Block Ford engines featuring an 8.2" deck height.
