{"product_id":"c-series-aluminum-intake-manifold-ford-240-300-l6","title":"C-Series Aluminum Intake Manifold, Ford 240\/300 L6","description":"The Offenhauser 6227C is an aluminum C-Series single-plane intake manifold engineered to enhance performance for Ford 240 and 300 cubic inch inline-six engines. Designed to bridge the gap between factory components and full-blown competition setups, this manifold aims to significantly improve torque delivery in the mid-to-upper RPM ranges, supporting a broad power band from 2,500 up to and beyond 7,000 RPM.\n\nConstructed from durable aluminum with a natural finish, the 6227C features a single-plane design optimized for airflow. It is specifically configured for square bore carburetors, offering versatility for various setups. While smaller applications can accommodate Holley 5200 or Weber 32\/36 Series 2-barrel carburetors (with an adapter for Holley 2300 competition use), the six-cylinder, 4-barrel configuration is ideal for square bore Holley or Carter carburetors.\n\nFor competitive applications, the emission-control provisions integrated into the manifold can be easily blocked off. The product description also highlights that when paired with headers and a cam, a Ford six engine equipped with this manifold (and potentially a Dual Port manifold) could see significant horsepower gains. One source indicates that dyno tests on a Ford six with the Offenhauser manifold, headers, and cam produced as much as 115 HP over the stock configuration. Another claim suggests that on a stock 240 or 300 CI engine, these manifolds can increase HP output by 50 HP.","brand":"Offenhauser","offers":[{"title":"Default Title","offer_id":52689316020536,"sku":"6227C","price":600.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687078288.jpg?v=1784905031","url":"https:\/\/store.motormia.co\/products\/c-series-aluminum-intake-manifold-ford-240-300-l6","provider":"MOTORMIA","version":"1.0","type":"link"}
