I was given a working Digital 6A box. Are there any benifits to me using it or is it not worth hooking up?

 

Do you have any evidence that your current ignition is not supplying adequate spark to the engine under max load?

The multiple spark boxes have most benefits for power adder applications like forced induction and nitrous. Your 12.8:1 SCR with the CC306 might need something for the relativley high dynamic compression ratio that you may have.
