Shake rattle and roll

Unfortunately the saga continues.
So I got a set of cut to fit wires and routed them in such a way that not a single wire touches any other. Not as pretty as the previous wires or routing but so be it.
No change in the surging, so after some reading I found edlebrocks are finicky about fuel pressure. My pump is pushing a steady 7-8 psi, so today I got a cheap mr. Gasket adjustable fuel pressure regulator. Drove it around gor 10-15 minutes and the car seemed happier than normal. Not sure as to the surging because when I stopped to get some gas the car started to die when I put it in gear. Continued to hard start and die for 5 minutes or so and then drove home with a crappy idle. Im guessing a crappy part, but I cant imagine theres much to this regulator. Probably just a ball valve or some equivalent. Could running the pump with too much pressure have damaged something in the carb to where it is giving me issues with the correct fuel pressure.
