I have the mopar performance orange box and distributor for small block in my car right now. I am converting to a big block which will come with a factory, stock electronic ignition, I don't physically have it yet so I have not had a chance to look at it. What I am wondering is, can I use the small block orange box kit (minus the distributor) with a factory big block electronic distributor, or do I need to buy the Mopar performance distributor for the big block?
