The big-pressure pump described was a generic "Airtex" brand stamped-together mechanical pump. I've heard of other guys having similar problems with the new pumps like that; I personally like the ones that screw together (I ran a real 50's AC-Delco pump I rebuilt on my 283).
I also think (IIRC) that the later SBC pumps (some of them, anyway) are spec'd at 6-8PSI to begin with, which everyone seems to agree is too much for the Carter carbs to deal with.
Never hurts to test the pressure and see what it is. If you search "sbc mechanical fuel pump pressure" you get a lot of results from pumps putting out too much pressure.
