Variable cam timing is nothing new. OHV Pushrod motors were first introduced in the mid 1900's. OHC motors have been around since the early 1900's. The DOHC engine design has been used by many car manufacturers for much longer than the pushrod motor has. Best you learn a bit about engine history before you go ranting about pushrods being older. The only thing older about the pushrod 302 when compared to the 4.6 and 5.0 dohc engines is that ford built their ohc engines after the ohv engines. That does not make pushrod engine technology "older" by any means. One design is also not better than the other any more than you can prove that ford is better than Chevy or vice versa. Different strokes and it all gets the job done. Fords dohc engines are far from new technology. Don't mean to burst your ford bubble. Sorry dude.
Wrong....
