Description

The Holley GM LS1/LS2/LS6 Modular Hi-Ram Intake Manifold is a cost-effective alternative to fabricated sheet-metal for high-performance applications where induction system height is not limited. It is designed for use on N/A or forced induction engines in the 6.0 to 7.0+ liter range, maximizing power at 7000-8000+ RPM. It features aggressive, bold, race-bred styling for various applications like drag race, muscle car, marine, off-road, sandrails, pulling trucks, track, and street-rods. The base is modular to accept a wide range of carbureted and EFI tops. EFI fuel rails are machined for -8AN O-ring Fittings. Construction is cast aluminum.
