    INSTALLATION NOTES: 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 sump Fox style 5qt oil pan and pickup (M-6675-A50), serpentine style water pump (M-8501-C50) and timing chain cover (M-6059-D351), 4-bolt harmonic damper (M-6316-M50) and valve covers (M-6000-K302R).
  • The rear sump style oil pan will work in all Fox body applications. For other style applications, see oil pans on pages 101, 103.
  • The timing chain cover (M-6059-D351) will work with most V-belt applications, see page 97 for other timing chain covers.
  • The water pump (M-8501-C50) will work on 1986-93 Mustangs. For other applications see pages 97-98.
  • The valve cover (M-6000-K302R) included will work on 1986-93 Mustangs, optional valve covers are available on pages 118-120.
  • The damper is production style 1981-95 Mustang. For other applications see pages 84-85.
