You guys rock!!! Thanks for the info. I rechecked the manual and I was wrong, it was 6 BDTC. I do have timing marks that go out past 12. I'm going to advance the timing a bit and see what happens. I don't have a tach on it yet, so the fancy timing you suggested will have to wait. While I'm at it, do you know how to get the original tach that was an option on the 67....it goes into dash on the rght side where the the oil pressure/altenator combo gauge is?

Heres my other question now. I've heard sometimes your engine can knock without you hearing it. How exactly will I know if its knocking?

Ok I lied, more questions. I realize that when you mod an engine, factory setting are out the door. But why do the mild mods (carb, intake, and headers) on my car warrant an increase in the timing? Is it because of more gas and air going in?

Finally, I also have a 1979 F100 302 with the same mild mods. Do you have a recommendation of the timing for it?
