{"product_id":"holley-hi-ram-lower-manifold-gm-ls7-300-228","title":"Holley Hi-Ram Lower Manifold - GM LS7 300-228","description":"• Runner length and the tapered cross-section designed to perform well for a wide range of engine configurations • 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. • Cast aluminum construction. • 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. • 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 LS7 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 LS7 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!","brand":"Holley","offers":[{"title":"Default Title","offer_id":50228744978709,"sku":"BBVL_300-228","price":849.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0845\/6844\/1109\/files\/300-228_01_P04_KIT.jpg?v=1791181591","url":"https:\/\/shop.davesusa.com\/products\/holley-hi-ram-lower-manifold-gm-ls7-300-228","provider":"Dave's Auto Center","version":"1.0","type":"link"}
