Description

Fits most GM Gen V LT Engines with OE-type LT Cylinder Heads

Part Number: 300-940BK

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. 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.
