This manifold is designed to work with Vortec cylinder heads that have four bolts per side for attachment, such as GM part numbers 12464298 and 12558060. Its aluminum construction and high-rise design are intended to optimize horsepower gains and provide a wide torque band for improved engine performance.\n\nThis intake manifold is compatible with square-bore 4150-style carburetors. It also features an externally plumbed hot water crossover passage, which can aid in fuel vaporization and consistent engine operation. For proper installation, specific manifold gaskets (P\/N 89017465) and attachment bolts (P\/N 12550027) are recommended.\n\nThe product is also subject to California Proposition 65 warnings regarding cancer and reproductive harm.","brand":"Chevrolet Performance","offers":[{"title":"Default Title","offer_id":52662748741944,"sku":"12366573","price":672.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/657713515.jpg?v=1784319774","url":"https:\/\/store.motormia.co\/products\/aluminum-high-rise-intake-manifold","provider":"MOTORMIA","version":"1.0","type":"link"}
