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\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/a94f98a6cca627bead20d256b78521ca.PDF\"\u003eWarranty\u003c\/a\u003e\u003cbr\u003e\u003cul\u003e\u003cli\u003eLarger Plenum and Runners Maximizes Other Upgrades\u003c\/li\u003e\u003c\/ul\u003e","brand":"Edelbrock","offers":[{"title":"Default Title","offer_id":47784273510594,"sku":"EDE75621","price":844.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/0784\/7874\/files\/1d5fbec4b2fc2b2838634faa14bbe54d.jpg?v=1781234005","url":"https:\/\/grocerygetterperformance.com\/products\/edelbrock-polished-b-b-chev-rect-port-rpm-air-gap-manifold","provider":"Grocery Getter Performance","version":"1.0","type":"link"}
