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!\u003cbr\u003e\n• 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. • Runner length and the tapered cross-section designed to perform well for a wide range of engine configurations\u003cbr\u003e\n• 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.\u003cbr\u003e\n• Cast aluminum construction.\u003cbr\u003e\n• 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.\u003cbr\u003e\nFeatures:\u003cbr\u003e\nBase Plenum Top Mounting Flange Height – 8.42” to the lifter valley cover flange on engine block.\u003cbr\u003e\nTotal Height with 92\/102mm EFI Plenum Top – 12.32” to the lifter valley cover flange on engine block.\u003cbr\u003e\nPort Size – 2.49” Height x 1.21” Wide\u003cbr\u003e\nMounting Flange Gasket Type – Standard LS3 Molded O-Ring\u003cbr\u003e\nPlenum Top Gasket Type – 3\/32” Round O-ring Cord\u003cbr\u003e\nThrottle Body Flange Location, with 92mm EFI Plenum Top : Height – 8.42” (from engine block lifter valley cover flange), Longitudinal Location – 3.84” (forward from engine block front flange), Angle – 25 deg.
