A dry sump would be the proper solution for that issue. This has been an issue for a long time if the SBC has enough of an rpm ceiling. I've never heard of it being a problem in street/stock trim. They don't have high volume pumps, just relatively higher pressure (70lb appears to be a common number). The flow at the top end is substantial in comparison to other pushrod engines.
What 2 quarts more would do is, perhaps (thinking), allow you a few more seconds of acceleration without starvation. I'm unsure about it since the cached supply is the same and the choke point is at the same point. The volume pumped would be the same (in a vacuum of theoretical perfection).
I don't think it will serve that need. Figure the 2 added quarts and plumbing being longer circuits inside the engine between the sump and the valve covers. The sump would go down just as fast. The valve covers would fill just as fast in that "surge".
Do you see how I'm reasoning this?
