I am getting a 70's volarie from a buddy for 2 cases of beer. It has a slant6 in it , but he had to advance the timing alot just to get the car started, I know the engine will need to be rebuilt but having to advance the timing is that a worn out cam? Just want to know what I may have to change and what I might be able to keep during the rebuild.
Does anyone have an idea what might cause the timing to have to be advanced like that?
