Product Description

When tested on a 466 CID engine, the new intake manifold proved 50 horsepower better than the best NASCAR single-plane counterpart and 100 horsepower better than the factory dual-plane manifolds supplied with 1969-1970 production cars. Un-ported, this Kaase intake has sustained over 1000 horsepower on a well-built 600 CID engine. Moreover, on an engine as small as 429 CID, it has supported full engine loads at 2300 rpm. The intake, which also fits any of the OEM Boss heads, is available for either the 4150-style (750-850 cfm) carburetors or 4500-style (Dominator) carburetors.
