Chevrolet V8's with high-performance rectangular-port heads. The open air space separates the runners from the hot engine oil, and as a result, the air\/fuel mixture stays cooler for a denser charge and more power. This intake manifold is a dual-plane, high-rise design with a 180 degree firing order to produce incredible top-end horsepower while retaining good throttle response. The larger plenum and runners match the free-flowing exhaust, high-lift cams and other modifications of a high output engine. They are intended for high-performance's street or competition engines that run up to 6500 rpm. Includes rear water outlets, two distributor clamp locations and nitrous bosses. Accepts all late model alternator and A\/C brackets for the street. For square-bore carbs only. No provision for exhaust heated chokes and no exhaust crossover. This manifold offers a polished finish for a brilliant shine and classic look.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBasic Operating RPM Range:\u003c\/strong\u003e 1500-6500 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Maximum Height:\u003c\/strong\u003e 5.220 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCNC Ported:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEGR Port:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Polished\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlange Type:\u003c\/strong\u003e 4150\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFront Maximum Height:\u003c\/strong\u003e 4.450 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGasket Or Seal Included:\u003c\/strong\u003e No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade Type:\u003c\/strong\u003e Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRear Maximum Height:\u003c\/strong\u003e 6.000 in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e RPM Air-Gap\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle Or Dual Plane Type:\u003c\/strong\u003e Dual\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVehicle Model:\u003c\/strong\u003e Chevrolet\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Edelbrock","offers":[{"title":"Default Title","offer_id":44849554129031,"sku":"EDE75621","price":1155.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0744\/4008\/1543\/files\/075621_v1.jpg?v=1788268624","url":"https:\/\/checkout.northernperformance.ca\/products\/rpm-air-gap-big-block-chevy-2-r-polished-intake-manifold","provider":"Northern Performance","version":"1.0","type":"link"}
