fuel problem 1968 chrysler newport 383 6.3L 2 barrel carb.

I was on the freeway driving, then all of a sudden it started to bog out. Got it home and it looked like my carburetor looked clogged and so I rebuilt it. and nothing changed and I messed with that for awhile then a just bought a carburetor as close to the old one that a could . Nothing changed so a replaced the fuel pump and the fuel lines plus filter. It'll start up if I put carb cleaner in the carb but it wont stay running and sounds pretty rough. I also put new plugs in too. I've tested vacuum to the mechanical fuel pump and it at around 4 and I think it should be 10ish. I want to fix it but I'm kinda lost on what to do next. Help!?
