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 Techline @ (800) 367-3788
for advice
regarding your specific application.
ACCESSORY COMPONENTS:
1. Front Accessory Drive
Must be selected for your particular application. This engine is equipped with a short serpentine reverse
rotation
water pump, timing cover and damper with an unbalance factor of 50 oz.-in. designed to be used with 1979-
93
Mustang front accessory drive components. If your application calls for the use of later model short
serpentine
or “V” belt components, consult the additional parts list for help.
2. Transmission
A. Engines designed for use with
Manual Transmissions
are shipped with a 157-tooth (13-1/4" dia.) flywheel
with a 50 oz.-in. unbalance factor.
B. Engines for use with
Automatic Transmissions
with a 164-tooth (14-1/4" dia.) flexplate with a 50 oz.-in.
unbalance factor use. These flexplates fit AOD or C-4 transmission applications. For C-4 transmission
applications with a 157-tooth (13 ¼" dia.) flexplate with a 50 oz.-in. unbalance factor, use Ford Racing part
M-6375-E302. The supplied flexplate
will not fit C-6 applications.
For use with a C-6 the flexplate needs
to be removed and replaced with Ford Racing part M-6375-J302.
