lol... good post Ram. I might suggest the timing curve isnt fast enough, and you can dial in more (closer to 40 total) centrifical if it likes the manifold vaccum setup. The only difference I can see with ported vs manifold vacuum is the part throttle drivability and milage, where (just my opinion) the ported helps more. Of course, with the light boxed up it's impossible to tell...lol.
