LS1/LS2/LS6 Cathedral Port EFI for 1 x 92MM Throttle Body – Black Ceramic CoatingMounting Flange Gasket Type â?? Standard LS3 Molded O-RingTotal Height with 92/102mm EFI Plenum Top â?? 12.32â? to the lifter valley cover flange on engine block.Runner Length â?? 6.58â?, As-Cast Runner Cross-Sectional Area â?? Tapered 4.25 in² to 2.53 in²Port Size â?? 2.49â? Height x 1.21â? WidePlenum Top Gasket Type â?? 3/32â? Round O-ring CordBase Plenum Top Mounting Flange Height â?? 8.42â? to the lifter valley cover flange on engine block.Throttle Body Flange Location, with 92mm 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)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?¢ 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.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?¢ 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.â?¢ Runner length and the tapered cross-section designed to perform well for a wide range of engine configurationsâ?¢ Cast aluminum construction.
