Can Anybody Identify This Distributor?..

I did check the rotor phasing on Wednesday and it is good. (Hole in cap/timing light method) The relationship of the rotor compared to the distributor gear slot was not the same as the mopar performance distributor. All I had to do was move my Spark plug wires over 1 terminal .
Motor seems to pull stronger as the revs approach and go beyond 4000 rpm. I was getting some breakup at higher RPM with the MP Distributor.

Cooler weather setting in, but I hope to do a few more test runs with it this weekend. It's vacuum advance mechanism is solid as compared to the wobbly plate mopar vacuum advance.

Eventually, I will lock it down and test it as the firing source for my Fitech EFI.
