Oddly, it can be more so on older engines. Pushrod engines have much
higher loads to the camshaft than modern OHC multi valve types. And a
worn cam may not stop it running, but will reduce the performance and
increase fuel usage.

Judging by the number of drivers I've known that failed to notice their
engine was firing on 3 not 4 cylinders, it might not get noticed ....

Dave is of course talking tosh. The load on the camshaft, all other
things being equal, does not change just because there is a pushrod
involved.

not until you use seriously high racing RPM where the pushrod mass has
some effect, anyway.

How many cars are pushrod nowadays?

You might ask Turnip why he's talking crap. But only to be expected. And
at various times he's claimed to be an engineer.

He is. You're not.

Not so long ago he claimed to be out in darkest africa designing a radio
system for the local dictator.
