So, the air\/fuel mixture stays cooler all the way to the heads, which produces a denser charge for more power. Runners are tuned to move the power band 1,000 rpm higher than Air-Gap manifolds, from idle to 5,500 rpm up to 1,500 to 6,500 rpm.\u003c\/p\u003e\u003cp\u003e- Notes: Includes standard oil fill , as well as early air conditioning support bracket accessory bosses.\u003c\/p\u003e\u003cp\u003e- Notes: Please Check the Compatibility Carefully before Placing an Order.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cp\u003eSpecification:\u003c\/p\u003e\u003cp\u003ePart Number: 7551\u003c\/p\u003e\u003cp\u003eIntake Manifold Height: 5.540\"\u003c\/p\u003e\u003cp\u003eBasic Operating RPM Range: 1500-6500\u003c\/p\u003e\u003cp\u003eIntake Style: Dual Plane\u003c\/p\u003e\u003cp\u003eIntake Material: Aluminum\u003c\/p\u003e\u003cp\u003ePart Type: Intake Manifold\u003c\/p\u003e\u003cp\u003eCylinder Head Type: Stock configuration\u003c\/p\u003e\u003cp\u003eEngine Block Deck Height: Standard deck\u003c\/p\u003e\u003cp\u003eCarburetor Mounting:4-barrel square bore\u003c\/p\u003e\u003cp\u003ePackage included:1*intake manifold \u0026amp; some parts shown in the picture\u003c\/p\u003e\u003cp\u003eVehicle Information:\u003c\/p\u003e\u003cp\u003e- Compatible with Oldsmobile 1968-1976 455 7.5L V8 Engine\u003c\/p\u003e","brand":"Haytalras","offers":[{"title":"Default Title","offer_id":48054902522115,"sku":"7551","price":279.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0816\/2374\/4771\/files\/Haytalras7551IntakeManifoldAirGapDualPlaneForOldsmobile1968-19764557.5LV8_main_5cf618c2-6700-4f51-84de-c73c5cd5857b.png?v=1783063951","url":"https:\/\/www.haytalras.com\/products\/oldsmobile-v8-air-gap-dual-plane-4150-intake-manifold-7551","provider":"HaytalrasAutoparts","version":"1.0","type":"link"}
