I only have the stock gearing for now as I recently got the engine installed and have been working to tune it the best I can until I have money to do the rear end. And stall doesn't matter because mine is a manual not an auto.
As far as the e-curve goes, I have my switches on 1-0 which is curve "J" 15 degrees all in by 3,000 rpm. So my initial is at 19 degrees with a 15 degree advance with no "vacuum advance" and a total of 34 degrees... HOWEVER... My actual total timing is about 37-38 degrees as it does go higher than the supposed 34 degrees if you add 19 and 15. So I set my total higher so the initial is more where I want it with the total kinda where I want it since this dizzy works the way it does. It is a very cool idea but doesn't work as well as it probably should.
