"Don't try." What I used to do with Chev EG was get it as close as I could, then just bump it until the pump drive engaged, then bump it back around "on the marks." If it wasn't where I wanted it, move it a tooth and try again. Once I finally learned that, it never took me more than once or twiice to "get it in." I don't remember Ford being any different. I have not set up many.
I DID have a 289 shear off a pump drive, someone had put a high pressure pump in after rebuild and "I guess" the factory allen shaft did not like that
