Thats pretty normal it seems.........
But I'd like to be rid of the Opti-Spark completely. A Distributor can be made to fit behind the LT1/LT4 Intake with just some minor machining. That being done, I don't see why the Opti couldn't be completely removed from the equation. As you said the Opti is basically acting as the distributor, but I'm "scared" so to speak of the downfalls it still has, and would hate to see any problems on a car of this magnitude.
I don't expect to get Sequential operation out of this, as I still wouldn't have a Cam Position sensor.....
