Trouble-shoot the output of the fuel pump, flow & pressure. If there was/is ethanol in the fuel the pump diaphragm or check valves may have been damaged while it was sitting. Same with the carb and its internal parts.

That Holley carb may have a filter screen inside the inlet fitting just before the float valve, sometimes they get overlooked and clogged.
