I'm sort of curious how a mildly ported lower with the stock lopo upper would do. That would at least even out the airflow without having too much intake to worry about. At some point it just has to be obvious that we're polishing turds though. Still, I got surprising improvements out of that Holley lower on my stock HO. A properly ported stock lower casting would be pretty comparable to the Holley piece.
