BBC F/P Block-Off Plate - Clear

The CSR Performance BBC F/P Block-Off Plate in clear anodized aluminum is a precision fuel pump blockoff solution engineered for Big Block Chevy engines undergoing fuel system modifications. This component eliminates the original fuel pump cavity when converting to alternative fuel delivery systems, providing a clean, finished appearance while maintaining structural integrity of the engine block.

Constructed from aluminum and finished in clear anodize, the block-off plate measures 4 x 0.75 x 6.9 inches and includes stainless steel Allen head fasteners for corrosion resistance and reliable clamping force. The included gasket ensures a proper seal between the plate and engine block, preventing oil seepage and maintaining a professional installation. Clear anodizing provides both aesthetic appeal and protective oxide coating while allowing the aluminum finish to remain visible—a preferred choice for engine bay builds where component visibility enhances the overall presentation.

This block-off plate is essential for Big Block Chevy engine builders and hot rodders performing fuel system upgrades, EFI conversions, or carbureted engine swaps. Installation requires basic hand tools and takes minimal time once the fuel pump cavity area is accessible. The lightweight design—just 0.19 lbs—adds no appreciable weight to the engine assembly, making it an invisible component in terms of performance impact while solving a critical finishing problem in custom engine builds.

Sold individually, this CSR Performance part (SKU CSI661C, MPN 661C) delivers the precision fit and quality finish expected by serious engine builders who understand that proper block sealing prevents oil weeping and protects internal components during extended operation.
