nope, you won't have to swap the dizzy, although if you haven't upgraded away from the points you might want to anyways, you can get away from points with the Duraspark II system, or the Petronix system
you might need to worry about the compression ratios for it though
as for other mods to go with it....
have you bought the Ford Six Handbook yet?
check in the shop section of the homepage, you should find it pretty easily, it should outline a good amount of steps
in the meantime, try searching through the past posts, i can almost guarantee that someone on here has done exactly what you want to do, or close enough to it that you'll be able to follow almost all of what they did
what car do you have?
