Holley 300-940 Single Plane Intake GM Gen V LT Fits Most GM Gen V LT Engines with OE-Type LT Cylinder Heads

This intake manifold is meant for GM Gen V Lt engines equipped with OE-type GM Gen V Lt cylinder heads where the intake flange bolt pattern and intake port opening locations match the OE Gen V Lt port configuration. This product is intended for OE direct injection and a 4150 EFI throttle body , but there are also other Holley accessories available to allow the installation of a GM LS 92mm or 105mm drive-by-wire throttle body (#17-93 and #17-94).

The 300-940 is meant for street and performance engine applications with 5.3 to 6.2+ liters of displacement and maximum engine speeds of 6000-7000 rpm (depending on the engine combination). Holley's new single-plane Gen V Lt intake manifold was designed with an optimized runner layout and constant cross-sectional area, resulting in a broad torque curve with the best vehicle performance from 2500-7000 RPM.

This single-plane design provides the lowest throttle body flange height possible while providing maximum performance all the way to 7000 rpm. The cast aluminum construction makes this manifold a great choice for centrifugal blowers, turbochargers, or Nos applications.

These intake manifolds are sold for pre-emissions control applications only and will not accept stock components and hardware.
