Distributor Identification?
I have a 77 302 in my F-100 and I am replaceing the Dizzy with a rebuilt one, I called arround the all around price is $50-$60. But one person told me I have to mesure my gear or bring it in... And I called the guys at NAPA and he said the only difference between gears is one is cast iron and one is steel? He told me to bring in my dizzy to make sure I am buying the right one, or just take it out and look and see if its cast iron? I think the one I have is steel, but am not positive it is steel? I didnt even know that they mad cast iron gears? I would think they would chew up the mateing gear (if it is steel) How can I tell? And what is best to buy? I dont want to be one of thoes guys that asks why he is geting metal shaveings in his oil filter and pull my new dizzy and find that it chew'd up my gears....

In the 80's(?) Ford started putting roller cams in the small block and they require a steel dizzy gear. The cast gear should work fine on yours.
Unless you turn the radio up too loud.

He's messing with you about the radio.
you have a hydraulic flat tappet cam, which is made of cast iron, therefore the distributor drive gear must also be made of cast iron. I am 103% sure of this, as I've swapped a roller motor into my '77, and had to send my distributor off to have a steel gear pressed on. Roller cams are made of billet steel, which requires the use of a steel cam gear. You cannot visually tell the difference, you have to go by how it is labled, and pull the distributor out after a few hundred miles and inspect the gear, to make sure that it is not chewed up at all. I have a cast iron gear on my desk right now that got chewed up by a billet steel cam, I"ll attach a picture of it later. Bottom line is, for your '77 motor, make sure that you get a distributor with a cast iron gear, and single vacuum advance. Should cost around $50 at Autozone, and come with a lifetime warranty. That is, of course, unless you like blasting that AM radio.....
