Re: Pushrod vs. SOHC vs. DOHC

OHV is certainly not superior, among other things already mentioned the pushrod intrusion through the cylinder head limits port design and shape. Of course more of the airflow differences between domestic and import cylinder head flow is due to the Big 3's reliance on displacement to make airflow rather than brilliant cylinder head design and RPM, but then either approach can work extremely well.
