GM GenV LT Lo-Ram Intake Manifold

The GM GenV LT Lo-Ram Intake Manifold by HOLLEY (MPN 300-715BK) represents a modern evolution in LS-platform induction technology, purpose-built for builders and enthusiasts seeking to optimize airflow on contemporary GM Gen V LT engines. This low-ram design targets the growing segment of street and race applications where factory intake geometry limits volumetric efficiency. Whether you're upgrading a stock LT1, LT4, or LT2 engine, this manifold addresses the fundamental challenge of delivering consistent, high-velocity air charge to all eight cylinders while minimizing heat soak and turbulence.

Holley's lo-ram configuration reduces the vertical stack height compared to traditional tall-ram designs, improving hood clearance for custom engine bay layouts while maintaining superior plenum velocity characteristics. The manifold's internal runner architecture is engineered to promote even fuel distribution and air mixing, critical for maintaining combustion consistency across the RPM band. At 33.23 pounds, the casting provides structural rigidity necessary for boost-ready applications, and the blackfinish option resists corrosion and heat discoloration over extended use. The compact footprint—16 inches wide by 15 inches deep—fits demanding swap scenarios where space constraints challenge conventional intake placement.

This intake manifold suits naturally aspirated and boosted Gen V LT powerplants in road racing, autocross, and street-performance builds. Compatibility is direct with factory LT cylinder heads and standard GM fuel rail systems; however, confirm your specific engine variant (LT1, LT2, LT4, or LT6) before purchase to ensure carb or EFI configuration alignment. Installation requires proper gasket sealing and torque sequencing to avoid coolant leaks; professional machine work is recommended for users unfamiliar with LS-family head work. The HOLLEY 300-715BK delivers measurable intake velocity gains—typically 8–15 horsepower on naturally aspirated builds—making it a foundational upgrade for any serious Gen V LT performance program.
