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! \u2022 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. \u2022 Runner length and the tapered cross-section designed to perform well for a wide range of engine configurations \u2022 Cast aluminum construction.<\/div>\n<h3>Features:<\/h3>\n<ul class=\"productpage_list\">\n<li>Mounting Flange Gasket Type \u2013 Standard LS3 Molded O-Ring<\/li>\n<li>Total Height with 92\/102mm EFI Plenum Top \u2013 12.32\u201d to the lifter valley cover flange on engine block.<\/li>\n<li>Runner Length \u2013 6.58\u201d, As-Cast Runner Cross-Sectional Area \u2013 Tapered 4.25 in\u00b2 to 2.53 in\u00b2<\/li>\n<li>Port Size \u2013 2.49\u201d Height x 1.21\u201d Wide<\/li>\n<li>Plenum Top Gasket Type \u2013 3\/32\u201d Round O-ring Cord<\/li>\n<li>Base Plenum Top Mounting Flange Height \u2013 8.42\u201d to the lifter valley cover flange on engine block.<\/li>\n<li>Throttle Body Flange Location, with 92mm EFI Plenum Top : Height \u2013 8.42\u201d (from engine block lifter valley cover flange), Longitudinal Location \u2013 3.84\u201d (forward from engine block front flange), Angle \u2013 25 deg.
