Installation notes:

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 front sump oil pan and pickup, Explorer "short style" timing cover and water pump, Explorer harmonic damper and EFI valve covers.
*The front sump oil pan may work for many late 60's and early 70's Ford passenger cars.
*The Explorer timingchain cover may work for 1994-95 Mustang, and 5.0L Explorer. For other applications use your original. M-6059-D351 replacement front cover may work for most other common applications.
*The water pump included may work for 5.0L Explorer.
*The valve covers included should work for most Mustang EFI applications.
*The damper may need to be changed to your original 1981 or newer (part number E4TZ-6316-A).
*The flywheel included should work for most 157-tooth manual transmission applications. For C-4or A0D automatic transmission applications use your 1981 or newer flexplate or order E2AZ-6375-A from your local Ford Dealer for a 164-tooth flexplate.
*Distributor with steel gear should be used to be compatible with the camshaft included in the engine.
*Firing order 1-3-7-2-6-5-4-8 (5.0L HO and 351W order).
*Built with current production parts.
