Modern pushrod designs aren't "sloppy" - when you don't need to rev as high to generate adequate power, you don't need the added valve stability that an overhead cam arrangement provides. Not to mention that a single camshaft actuating pushrods is more space and weight efficient than a set of overhead cams.

But then, that's just my opinion as someone who races a modern, fuel injected, naturally aspirated, RWD vehicle. A vehicle which has a pushrod V8.
