Holley 300-940 Lt Low Rise Intake, Natural

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).

EFI Fuel System Type, 2500-7000 RPM Range, Aluminum

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).
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.
2500-7000 RPM power band
4150 / 4160 Square bore flange
Optimized runner layout and constant cross sectional area - broad torque curve, best vehicle performance from 2500-7000 RPM
