I've seen plenty of guys in the mid 11s with an Air Gap but below that single plane is what I'd want. The Strip Dominator made 503 lb ft of torque and didn't fall below 437 between 3,900-6,000 rpm so I know it works OK. Could it be better? Probably. That's the question here - do I attempt to make the SD "better" with more porting (I'm obviously not an intake porting expert) or just spring for the Victor. Just seems like the Victor would have a slight advantage but that's just a hunch.
Maybe put it in these terms - if there needs to be money spent to get a better flowing intake, I would think the Victor would be the better choice to start.
