Holley LS Hi-Ram EFI Manifold GM LS1/LS2/LS6
LS1/LS2/LS6 Cathedral Port EFI for 1 x 105MM Throttle Body
Throttle Body Flange Location, with 102mm EFI Plenum Top : Height â?? 8.42â? (from engine block lifter valley cover flange), Longitudinal Location â?? 3.84â? (forward from engine block front flange), Angle â?? 25 deg. (down from vertical)
Mounting Flange Gasket Type â?? Standard LS3 Molded O-Ring
Total Height with 92/105mm EFI Plenum Top â?? 12.32â? to the lifter valley cover flange on engine block.
Base Plenum Top Mounting Flange Height â?? 8.42â? to the lifter valley cover flange on engine block.
Port Size â?? 2.49â? Height x 1.21â? Wide
Plenum Top Gasket Type â?? 3/32â? Round O-ring Cord
Runner Length â?? 6.58â?, As-Cast Runner Cross-Sectional Area â?? Tapered 4.25 in² to 2.53 in²â?¢ EFI fuel rails are machined for -8AN O-ring Fittings with passages large enough to accommodate high fuel flows and dampen pressure pulsations in the fuel system and come standard with EFI Hi-Ram kits.
â?¢ The base is designed to be modular in configuration to accept a wide range of carbureted and EFI tops and to be attractive to builders and fabricators as the foundation for custom induction systems.
â?¢ Intended for use on N/A or forced induction engines in the 6.0 to 7.0+ liter range, max power at 7000-8000+RPM.
The Holley GM LS1/LS2/LS6 Modular Hi-Ram Intake Manifold is introduced as a cost effective alternative to fabricated sheet-metal for high-performance applications where induction system height is not limited. Coupling this Hi-Ram intake with the high flowing LS1/LS2/LS6 style cylinder heads has outstanding potential for N/A and forced induction applications at a budget-minded cost. Aggressive, bold, race-bred styling will make bad intentions clear for drag race, muscle car, marine, off-road, sandrails, pulling trucks, track, street-rod applications and more!
â?¢ Cast aluminum construction.
â?¢ Runner length and the tapered cross-section designed to perform well for a wide range of engine configurations
