Agree although the limits were there & known about long before Nissan started using this engine. The rev limit in particular always meant to me that the pushrod engines would still be effective.

A choice of more compact pushrod layout, which interestingly enough, all Formula 1 engine manufacturers have opted against until the present day.

In a completely different formula, where engine revs were not restricted and the cars a much lower weight, with free final drive and gear ratios then DOHC engines make all the sense in the world.
In a rev-restricted, parity touring car set of regs, the DOHC engines are OK but not world beaters and so far have struggled to deliver in the way that some thought they would.
