{"product_id":"bbc-performer-rpm-a-g-manifold-r-p-polished","title":"Edelbrock Polished RPM Air-Gap BBC Rect Port Intake Manifold","description":"Edelbrock part #75621 RPM Air-Gap 2-R intake manifold is designed for street 396-502 c.i.d. 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.","brand":"Edelbrock","offers":[{"title":"Default Title","offer_id":48212240171256,"sku":"BDVJ_75621","price":803.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1538\/7640\/files\/EDE75621.jpg?v=1775686285","url":"https:\/\/nadersautosupply.com\/products\/bbc-performer-rpm-a-g-manifold-r-p-polished","provider":"Nader's Auto Supply","version":"1.0","type":"link"}
