PARTS INCLUDED:
1986-93 5.0L HO Mustang Production Engine Assembly
GENERAL INFORMATION:
This engine assembly is built with the Production 5.0L crankshaft, rods and hypereutectic pistons, resulting in a 50 oz.-in.
unbalance factor. The damper and flywheel/flexplate included are compatible with this balance specification. The damper
and flywheel/flexplate combination for your particular application may need to be re-balanced or modified for compatibility.
(See #1 and 2 for more details on balance).
Although this engine is intended to be a direct replacement for 1979-93 5.0L Mustang, it can be adapted to any 289/302
situation. Consult your Ford Racing dealer or call the Ford Racing Tech “Hot Line” @ (586) 468-1356 for advice regarding
your specific application.

unbalance factor use. These flexplates fit AOD or C-4 transmission applications. For C-4 transmission
