Starting a BB Duster project

Andy, I am thinking about the Holley Sniper for another project. I am curious as to how it controls timing, and what hardware you need to go along with it. I currently have a stock Chrysler ignition, but I also have an MSD Pro Billet distributor and 6A module, new in the box. I know you have gone a different direction with your project, but I figure you must have a pretty good understanding of how it works to do that.
