Take those nice screens out of the drain backs in the block as well as the vent pipes you screwed in the lifter valley. I bet it has a vac pump on it too. The oil rope that builds up around the rotating assy can keep the oil out of the sump. Get a good windage tray & pan combination on it that scrapes the oil back to the sump.
Those long stroke SBC's need the "right" pan and windage control.
Keep in mind your 434 has a lot more movement above the oil pickup than a 327 or 350.
