Small block distributor #3755820?

Hey all, I just pulled a dist out of my Ramcharger with #3755820 on a green tag. Does anyone have a source for the specs on it? Is it a performance dist, or just a stocker? I replaced it with a brand new MP unit (got a smokin deal on it ) with no noticeable difference in performance is why I ask. It would be nice to know what it is before I repair the vac advance and use it on something else. What say the board?

3755820 is stock for late '74 trucks with the 360 4BRL.

Holy crap, that must mean it's the original dist in my 74 Ramcharger I'll be dipped.
