Hi Ram Itake Base - Carb LS1/LS2/LS6

The Holley Hi-Ram Intake Base for Carb LS1/LS2/LS6 is a purpose-built carburetor mounting platform engineered for high-performance LS engine swaps and naturally aspirated builds. Designed by industry-leading Holley, this intake base addresses a critical need for LS-platform builders seeking reliable carburetor compatibility without sacrificing airflow or mechanical efficiency.

The intake base features a precision-cast aluminum design that optimizes plenum volume and fuel distribution across all intake runners, ensuring balanced air velocity and consistent cylinder charging. Its robust construction handles the thermal and mechanical demands of high-RPM operation while maintaining tight port-to-manifold sealing. The casting geometry is specifically matched to LS1, LS2, and LS6 head configurations, eliminating port mismatch losses that plague generic adapters.

This intake base is ideal for builders who prefer carburetor simplicity and tuning control over fuel injection complexity, particularly in vintage-styled hot rods, street cars, and bracket racing applications. With a substantial weight of 25.78 pounds, it delivers the structural integrity necessary for sustained boost environments and extended wide-open-throttle duty, while its compact footprint accommodates tight engine bay installations.
