Magnum and Wiring Swap

In another thread about test running the engine here: Attempt at test running a Magnum
I was given great advice by knowledgeable guys on this forum. One thing that was recommended was mechanically zero the timing. I went through that procedure and haven't moved the distributor since. I'll put a timing light on it to see where it is. I know moving distributor on this engine is not the same as on a regular engine since it picks up the crank position signal from the flywheel. I'm thinking the rotor might be out of phase with the cap.
