GM Gen V LT Single Plane
Intake Manifold
NEW PRODUCT RELEASE
Holley’s Gen V LT single plane intake manifold uses a low-profile 4150/4160 square bore flange for maximum hood
clearance. Intended to be used with OE Direct Injection alongside a Holley 4150 4 BBL Universal or GM DBW throttle
body, the 300-940’s cast aluminum construction is a perfect fit for power adders such as turbochargers, centrifugal
superchargers, and nitrous oxide.
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 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, an EFI elbow and throttle body combo, or one of our adapters that allow
the installation of a GM LS 92mm or 105mm drive-by-wire throttle body (#17-93 and #17-94). The latter pairs perfectly
with one of our new LS3 drive-by-wire air cleaners that are now available in standard round and dual snorkel designs
with chrome or black finishes. The 300-940 is designed 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.
