Greenwater,

Greetings from California!

In looking at the 2001 Ford Racing catalog: PN M-12390-B is indeed a steel gear, but it has NO color. The application is for 302's with steel production cam's. It should work on a 289, though the application doesn't say so. (Ford didn't build a 289 roller). Sounds like your cam is in and running so it obviously does work in the 289. That may solve one problem.

PN M-12390-A is for a 289/302 flat tappet cam. It is iron, it is also orange. PN M-12390-C is a Bronze gear, colored bronze.

The gear you need is going to depend on the inside diameter of your distributor. All 289/302/351W use a 1.249" outside diameter gear. There are two different inside diameters (slides over the distributor shaft) 0.467" which are generally for the 289/302's flat or roller, and 0.531" which is for the 302/351 flat and roller cams. Consideration needs to be given to the distributor you have.

Are we all thoroughly confused now?
