A different performance oil pan and pickup may be required for your application. Call the Techline at (800) FORD788 for more information.
The timing chain cover will work with most regular rotation water pumps.

A standard rotation water pump is installed on the engine. Other applications may require different water pumps and timing chain covers found on pages 97-98.
The valve covers (M-6582-R302) should fit most non-EFI applications, optional valve covers (sold separately) are available on pages 118-120.

The flywheel (M-6375-D302) not included should work for most 157-tooth manual transmission applications. For other transmission applications use the proper “0″ balance flywheel, see pages 127-128.
