Description
Holley EFI LS Hi-Ram intake manifold bases are cost-effective alternatives to fabricated sheet metal for high performance applications where induction system height is not limited. Coupling these cast aluminum Hi-Rams with the high flowing LS-style cylinder heads has outstanding potential for N/A and forced induction applications at a budget-minded cost. These modular lower manifolds accept a wide range of carbureted and EFI tops, making them attractive to builders and fabricators as the perfect foundations for custom induction systems. Fuel rails are included and machined for -8 AN O-ring fittings with passages large enough to accommodate high fuel flows and dampen pressure pulsations in the fuel system. The aggressive, bold, race-bred styling of Holley GM LS modular Hi-Ram lower manifolds will make bad intentions clear for drag race, muscle car, marine, off-road, sand rails, pulling trucks, track, and street-rod applications.
