I have a bit of a problem, I just bought a 69 Lincoln that doesn't run, and I am trying to get my classic to run properly so I can determine all what is salvageable upon rebuilt... and every time I go to the part store, they tell me the parts I need are no longer available. but when I have them run a search for a 70's Ford truck w/ a 460, the parts are available... I understand that perhaps the crack, and cam may be different, but does this include bolt-on accessories as well? ... So, my question is this... is there a actual difference or is my theory correct?
