I am not very experienced with SB Fords. I have an 89 GT donor. I am going to convert it to a carb fuel system. Are the distributers interchangable across years? Will an older style 302 distributer work on this motor or do I have to worry about the distributer gears? Are there any other pitfalls I need to worry about? This is my first Ford. I am usually a GM person, but the Cobra is too cool! Thanks for the help.
