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! • 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. • 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. • Cast aluminum construction.\u003c\/div\u003e\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul class=\"productpage_list\"\u003e\n\u003cli\u003eTotal Height with 92\/102mm EFI Plenum Top – 12.32” to the lifter valley cover flange on engine block.\u003c\/li\u003e\n\u003cli\u003eRunner Length – 6.58”, As-Cast Runner Cross-Sectional Area – Tapered 4.25 in² to 2.53 in²\u003c\/li\u003e\n\u003cli\u003eBase Plenum Top Mounting Flange Height – 8.42” to the lifter valley cover flange on engine block.\u003c\/li\u003e\n\u003cli\u003ePort Size – 2.49” Height x 1.21” Wide\u003c\/li\u003e\n\u003cli\u003eMounting Flange Gasket Type – Standard LS3 Molded O-Ring\u003c\/li\u003e\n\u003cli\u003ePlenum Top Gasket Type – 3\/32” Round O-ring Cord\u003c\/li\u003e\n\u003cli\u003eThrottle 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.
