The arguments here against pushrod motors would be more compelling if even Ford themselves believed in them. Do you find it curious that the implication is that a few guys on an enthusiast website know more about this than FMC does? I'd be more swayed that OHC is the way to go if there weren't examples of normally aspirated pushrod V8s making gobs of torque and 500+ horsepower, all without the use of expensive blowers.
