Droc,
Have you dyno'd it yet? What pipes did you put on it? Was there a particular reason you went with the Harley Fuel injection over something else like Horsepower Inc, Zippers, Speeds, Kuryakin?
Did you go with the heavy belt / side car belt when you made this change if not my best guess is your going to be

Did you do a speedo change over using the S&S kit so you can dial in the speed changes since you changed the countersprocket to a 21 tooth from a 25 tooth?
Did they happen to mention leaving the 25 / 36 alone and putting and going 30/70 on the belt drive?
I am wondering why you stayed with a chain drive cam vs. a gear drive?
Did you do any additional headwork to the SE Heads you bought?
Tell us how does it run? Would you recommend it to others? How long where you down? Did you put a timken bearing in since the cases were split anyhow?
Sorry not many have taken the plunge and hope you dont mind sharing.
