I have a 66 that I bought a rebuilt 302 for,I'm trying to figure out what starter needs to go in,it has a c4 tranny in it.The flex plate from the 289 is smaller than the one I got with the 302.The one for the 302 is 164 tooth but i'm not sure what year the 302 is.(a want to say late 60's)I want to get a smaller starter instead of the huge one that came with the 289.How do I find out wich starter to get.
