WARNING: Before installing the DynaForce Starter disconnect the battery cables. When disconnecting
the battery cables, always remove the Negative (-) cable first and install it last.
IMPORTANT: Proper installation of the DynaForce Starter is important to the overall operation. Correct alignment
of the starter pinion with the ring gear is needed to achieve the best operation and longevity from
your starter. Please read the instructions before attempting the installation.
When selecting a starter for your Ford, our research has found that year, model and drivetrain
combination do not always dictate the correct starter. There are variations between the 164 tooth and
157 tooth flywheels and well as the inside diameter of the starter block plate (4.130” or 4.084”). MSD
offers two starters for the 289/302 and 351W engines; one with a 3/8th depth ring gear, one with a
¾” depth. Figure 1 shows the differences and applications.
