About this product
This chrome steel block-off plate covers the mechanical fuel pump opening on Chevy Big Block Mark IV engines that have been converted to an electric pump or alternate fuel delivery setup. The chrome finish gives a clean, finished engine bay appearance while properly sealing the mounting location.
Confirm gasket condition, bolt pattern, fastener length, and sealing surface before installation — proper sealing helps prevent oil seepage at the mounting location. This plate is designed for carbureted applications using the matching mechanical fuel pump mounting pattern and is not intended for EFI fuel systems unless used with a properly designed conversion.
