{"product_id":"edl-75621","title":"RPM Air-Gap Big Block Chevy 2-R Polished Intake Manifold","description":"\u003cp\u003eEdelbrock 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.\u003c\/p\u003eRPM Air-Gap Big Block Chevy 2-R Polished Intake Manifold","brand":"Edelbrock","offers":[{"title":"Default Title","offer_id":44472052088897,"sku":"75621","price":787.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0740\/2500\/9217\/files\/0abbd83b-52dc-41a6-8a8c-2ed3c99d5932.jpg?v=1787624525","url":"https:\/\/www.theefistore.com\/products\/edl-75621","provider":"The EFI Store","version":"1.0","type":"link"}
