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\u003cp\u003eMANIFOLD |  1965-00 BB CHEVY 395-454 |  RECT PORT |  RPM AIR-GAP |  POLISHED\u003c\/p\u003e","brand":"Edelbrock","offers":[{"title":"Default Title","offer_id":51774824775992,"sku":"E003 75621","price":953.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/horsepower-asset-39946-5103003-square.webp?v=1779480756","url":"https:\/\/store.motormia.co\/products\/edelbrock-polished-b-b-chev-rect-port-rpm-air-gap-manifold","provider":"MOTORMIA","version":"1.0","type":"link"}
