At 10.55 pounds, MSD's APS starter for Fords (PN 5090) is nearly 51/2 pounds lighter than the stock version we removed from our '67 Mustang subject car. Installation is a few extra steps beyond just a two-bolt R&R operation, but it's still a relatively straightforward weekend-afternoon project. This starter fits vintage 289, 302, and 351W engines with automatic transmissions, as well as 5.0s with automatics and five-speeds. It can't be used on early three- and four-speed applications because the flywheels are closer to the starter mount surface and will prevent the starter gear from separating from the flywheel. It fit our '67 because the car has a late-model T5 five-speed transmission and a late-model-style bellhousing.
