EFI STARTER
I noticed that the starter on the 4.9 of the EFI years is quite a bit smaller than the older style. Does anyone know if that small starter will work on a non efi block?
Does anyone know why they are smaller? Is it a a better design?

These folks sell a mini starter that fits '65 - '96 300s, so reasonable to assume how the starter mounts didn't change throughout the run of the engine.

The good news is that this concept should lessen the chance of the old-style fender-well solenoid seizing up and running your starter constantly. (not as much amperage needed to flow thru it...it's done down below.)

The new starter is a permanent magnet design that Ford went to in the late 80's and 90's for most of their products I believe. It works similar to gm style utilizing a constant hot feed to the massive solenoid down below, then actuating it by a smaller lead from the fender-well solenoid. Good starter, just needs a little wiring. The diagrams are all over the net.

Some years back I went to Auto Zone for a replacement starter (warranty) for my 83 300. They said the part number had changed. I was suspicious, but installed it. It cranks faster than the old number, and no wiring change at all.

It appears that 1992 is the first model year for the smaller high density permanent magnet design with integrated solenoid.
The pinion gear on this smaller starter has 10 teeth.
The previous larger starter design has 9 teeth.
Looked up the tooth count on the flywheel and flexplate for 1982 & 1992
Both 1982 & 1992 have 164 teeth with 12 pitch, 14.23" outside diameter.
The 10 tooth pinion must be larger in diameter than the 9 tooth pinion to mesh with the 164 tooth flywheel/flexplate and therefore, spin the engine slightly faster.

Anyone using these starters? If so, how well have they performed?
Thanks, jack

The million dollar question is: Will this starter allow for removal/installation w/o having to remove the intake and header when using a headman header? I certainly like the 40% more torque with far less drain on the battery.
