See engine installation and tuning tips on page 40.
Some or all of the following items may need to be changed from your original engine
or modified for proper installation:
This engine has a rear T-sump performance oil pan and pickup, regular rotation timing cover and regular rotation water pump, and non-EFI valve covers.
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.
Fuel pump eccentric M-6287-B302 installed, allows use of mechanical fuel pump
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-BOSS) should fit most non-EFI applications, optional valve covers (sold separately) are available on pages 118-120.
The damper M-6316-C351 may require a spacer for pulley alignment, see page 85.
The flywheel (M-6375-A302) not included should work for most 157-tooth manual transmission applications. For other transmission applications use the proper 28 oz. flywheel, see pages 127-128.
