Show original supplier description
The Offenhauser Dual Port intake manifold is engineered to enhance the performance of Ford 240-300 cubic inch inline 6-cylinder engines. This manifold is designed to accept a variety of 4-barrel square bore carburetors, such as those from Holley, Carter AFB, and Edelbrock, with a bolt pattern of 5.160" x 5.625". This intake system is reported to deliver up to a 30% increase in power, offering a significant performance upgrade for these legendary Ford inline-six engines. The dual-port design aims to optimize airflow and fuel distribution for improved combustion efficiency. It is important to note that some installations may encounter clearance issues with the exhaust manifold, particularly with one-piece exhaust designs found on some 1983 and later setups. Users may need to consider alternative exhaust manifold configurations or fabricate custom solutions for proper fitment. Offenhauser offers specific manifold options, like the Series C (part# OF6227C), for those seeking 500 CFM and larger carburetor compatibility.
