What is this?

Do you think the best course of action would be to find an oem used mopar distribution block instead of trying to fix the ford one already on the car? I've never ripped into one so I'd have to learn how to plumb it. I have someone that's willing to sell a good used oem mopar distribution block for $75. I might just go with that. Should I keep that master or go with something else? Never dealt with this stuff so I don't know what setup would be best for this car. Thank you for the help
