Speedmaster PCE149.1005 Ford 351C Cleveland Supercharger Adapter Plate for 6/71 Blower

The Speedmaster PCE149.1005 is a precision adapter plate designed to bridge Ford 351C Cleveland carburetors to 6/71 supercharger manifold applications. This adapter plate enables direct bolt-on fitment between twin carburetors on your Cleveland engine and a 6/71 blower installation, making it an essential component for forced-induction engine builds.

This adapter is engineered for high-performance engine swaps and supercharger conversions where original manifold spacing doesn't align with modern blower specifications. The plate-only design allows builders to integrate their existing dual carburetor setup with upgraded supercharger systems without requiring complete manifold replacement. Ideal for hot rod, street machine, and performance restoration projects that demand compatibility between classic Cleveland powerplants and contemporary forced-induction technology.
